As US doors narrow, African tech talent faces a tougher path to America

On Tuesday, December 16, US President Donald Trump expanded travel and visa restrictions on nationals from more than 30 countries, many of them in Africa, reviving and widening a policy first introduced during his first term.

The order imposes full or partial entry restrictions based on visa overstay data, terrorism risk assessments, and failures in identity management and information sharing. For Africa’s fast-growing tech ecosystem, the move creates an entry barrier to one of the most important corridors for founders and operators trying to access the US market.

Trump’s decision followed a months-long bureaucratic process rooted in legal precedent, immigration data, and national security doctrine that has already survived Supreme Court review.

What led to the blanket ban

The current expansion traces back to June 2025, when Trump restored the travel restrictions from his first term shortly after returning to office. Rather than introducing a new framework, the administration reinstated Executive Order 14161 and Proclamation 10949, relying on an earlier Supreme Court ruling that upheld the president’s authority to restrict entry on national security grounds.

This time, the administration leaned heavily on data from the Department of Homeland Security’s FY 2024 Entry and Exit Overstay Report. Countries whose citizens overstayed US visas at high rates were flagged for sanctions, ranging from partial suspensions of business and student visas to full bans on entry.

According to that report, several countries’ citizens defaulted at notable rates. F, M, and J student and exchange visa holders were flagged as compliance risks due to overstays. Cote d’Ivoire recorded a 19.09% overstay rate among students and exchange visitors, while Tanzania and Senegal posted rates of 13.97% and 13.07%, respectively. 

Nigeria, one of Africa’s largest tech hubs, recorded a student and exchange visa overstay rate of 11.90%, even as business visa defaults on B-1 and B-2 visas remained just above 5%. The Gambia, Benin, and Sierra Leone stood out with the highest student visa overstay rates, each exceeding 35%, placing them among the most heavily penalised countries in the proclamation.

High overstay rates in any major category are treated as evidence of systemic non-compliance, triggering broad restrictions that hit African talent.

Several African countries now face full US entry bans, including Burkina Faso, Chad, the Republic of the Congo, Equatorial Guinea, Eritrea, Libya, Mali, Niger, Sierra Leone, Somalia, South Sudan, and Sudan. Sierra Leone was upgraded from partial to full restrictions under the new order, reflecting a sharp tightening of enforcement.

Other African countries were partially restricted. Nigeria, Senegal, Tanzania, Zambia, Zimbabwe, Angola, Benin, Burundi, Togo, Cote d’Ivoire, The Gambia, Malawi, Mauritania, and Gabon are subject to limits that primarily affect business, tourism, and student visas, while leaving some immigrant pathways technically open but more difficult to access.

Partial restrictions suspend the issuance of B-1 and B-2 visas used for business and tourism, as well as F, M, and J visas for students and exchange visitors. Some immigrant visa categories remain open, but applicants should expect slower processing and tougher reviews at US embassies.

“This is not a blanket ban on all immigrant visas,” said Oluyomi Ojo, founder of immigration consulting firm AgoraVisa. “It does not automatically shut down EB-1A and EB-2 visas. EB immigrant visas are affected at the consular level—embassies will not adjudicate or will effectively pause issuance—there will be no exceptions. EB migrations will continue as the ban does not affect approvals at the USCIS. The USCIS continues to adjudicate EB petitions inside the United States for all. The disruption happens at embassies, where visa issuance may be paused or delayed, even after approvals.”

Yet for Nigeria and several Sahel countries, the proclamation adds another complication. Trump explicitly cited the presence of groups such as Boko Haram and the Islamic State, arguing that terrorist activity “creates screening and vetting difficulties.” This could trigger enhanced security checks and reviews that slow immigration processes.

Those two factors combine to raise the burden of proof for Nigerian applicants across nearly all non-immigrant categories.

What does this mean for African tech talent?

The most immediate impact falls on global mobility. New B-1 and B-2 visas will largely stop flowing from affected countries, cutting off US access. Student and exchange routes, which were viable immigration routes into the US tech ecosystem, will also narrow sharply.

As visiting routes close, African tech talent is likely to seek out immigration pathways that remain unaffected by the proclamation. Employment-based visas such as O-1, L-1, and H-1B remain legally open, but they are far harder to obtain. These categories require employer sponsorship, exceptional-ability thresholds, or intracompany transfers that many early-stage founders and independent operators cannot meet.

“Tech workers already on O-1, L1, H-1B [visas] from [affected] countries are not impacted, and can still file for EB-1 and EB-2 in the US and get approval,” said Ojo. “Those with visas approved before January 1 face fewer issues.”

The deeper shift lies in how applications will now be judged. High overstay rates push consular interviews toward suspicion rather than validation. Immigration interviews will focus more on reasons an applicant might stay than on the purpose of the trip. African tech workers could face pressure proving they have reasons to return home, such as property ownership back home or long-term local employment, with no incentives to overstay their welcome. This creates a structural mismatch; for those without clear proof, it could weaken their ability to demonstrate ties to home countries.

Founders already inside the US system remain shielded from the executive order. But first-time entrants will face a wall built from data, security logic, and bureaucracy that hamper migration opportunities for African talent. This could encourage a shift toward alternative hubs in Europe, the Middle East, and Asia, where visa access is predictable.

What is Ethereum’s Fusaka Upgrade? Everything You Need to Know

What is Ethereum’s Fusaka Upgrade? Everything You Need to Know

Over the past few weeks, one of the most talked-about topics within the crypto community has been Ethereum’s Fusaka upgrade. What exactly is this upgrade, and how does it affect the Ethereum blockchain and the average crypto investor? This article will be the only explainer guide you need to understand the details of this upgrade within the Ethereum ecosystem. Why Does Ethereum Undergo Upgrades? To understand what the Fusaka upgrade will achieve, it is essential to comprehend what Ethereum’s upgrades aim to accomplish. The layer-1 Ethereum network was originally designed as a proof-of-work (PoW) blockchain. This implied that miners were actively behind the block mining process. While this consensus mechanism ensured security for the L1 blockchain, it also triggered slower transactions. The Ethereum development team unveiled a detailed roadmap, outlining various upgrades that will fix most of the network’s issues. These problems include its scalability issue, which refers to the network’s ability to process transactions faster. Currently, the Ethereum blockchain processes fewer transactions per second compared to most blockchains using the proof-of-stake (PoS) consensus mechanism. Over the past decade, Ethereum’s developers have implemented most of these upgrades, enhancing the blockchain’s overall performance. Here is a list of the upgrades that Ethereum has undergone: Frontier: July 2015 Frontier Thawing: September 2015 Homestead: March 2016 DAO Fork: July 2016 Tangerine Whistle: October 2016 Spurious Dragon: November 2016 Byzantium: October 2017 Constantinople: February 2019 Petersburg: February 2019 Istanbul: December 2019 Muir Glacier: January 2020 Berlin: April 2021 London: August 2021 Arrow Glacier: December 2021 Gray Glacier: June 2022 The Merge: September 2022 Bellatrix: September 2022 Paris: September 2022 Shanghai: April 2023 Capella: April 2023 Dencun (Cancun-Deneb): March 2024 Pectra (Prague-Electra): May 2025 Most of these upgrades (forks) addressed various Ethereum Improvement Proposals (EIPs) geared towards driving the blockchain’s growth. For instance, the Merge enabled the transition from the PoW model to a proof of stake (PoS) algorithm. This brought staking and network validators into the Ethereum mainnet. Still, this upgrade failed to unlock the much-needed scalability. For most of Ethereum’s existence, it has housed layer-2 networks, which leverage Ethereum’s infrastructure to tackle the scalability issue. While benefiting from the L1 blockchain’s security and decentralization, these L2 networks enable users to execute lightning-fast transactions. Last year’s Dencun upgrade made transacting on layer-2 networks even easier with the introduction of proto-danksharding (EIP-4844). Poised to address the scalability issue, this upgrade introduces data blobs. You can think of these blobs as temporary, large data containers that enable cheaper, yet temporary, storage of transactions on L2 networks. The effect? It reduces gas fees, facilitating cheaper transaction costs on these L2 rollups. The Pectra upgrade, unveiled earlier this year, also included EIPs addressing the scalability issue plaguing the Ethereum ecosystem. The upcoming upgrade, Fusaka, will help the decade-old blockchain network to become more efficient by improving the blob capacity. What is Ethereum’s Fusaka Upgrade? Fusaka is an upgrade that addresses Ethereum’s scalability issue, thereby making the blockchain network more efficient. As mentioned earlier, Fusaka will bolster the blob capacity for layer-2 blockchains, which refers to the amount of temporary data the network can process. This will help facilitate faster transactions on these L2 scaling solutions. It is worth noting that upon Fusaka’s completion, users will be able to save more when performing transactions across layer-2 networks like Polygon, Arbitrum, and Base. The upgrade has no direct positive impact on the L1 blockchain itself. On September 18th, Christine Kim, representing Ethereum core developers, confirmed the launch date for Fusaka via an X post. Following an All Core Developers Consensus (ACDC) call, the developer announced that the Ethereum Fusaka upgrade will take place on December 3rd. Ahead of the upgrade, there will be three public testnets. Fusaka will first be deployed on Holesky around October 1st. If that goes smoothly, it will move to Sepolia on October 14th. Finally, it will be on the Hoodi testnet on October 28th. Each stage provides developers and node operators with an opportunity to identify and address bugs, run stress tests, and verify that the network can effectively handle the new features. Running through all three testnets ensures that by the time the upgrade is ready for mainnet, it will have been thoroughly tested in different environments. Crucial to the Fusaka upgrade are the Blob Parameter Only (BPO) forks, which will enhance the blob capacity without requiring end-users of the blockchain network to undergo any software changes. For several months, the Ethereum development team has been working towards unveiling the BPO-1 and BPO-2 forks. Blockchain developers have pooled resources to develop Fusaka through devnets. Following performances from devnet-5, developers within the ecosystem confirmed that the BPO upgrades will come shortly after the Fusaka mainnet debut. Approximately two weeks after the mainnet launch, on December 17th, the BPO-1 fork will increase the blob target/max from 6/9 to 10/15. Then, two weeks later, on January 7th, 2026, the BPO-2 fork is expected to expand capacity further to a metric of 14/21. Ultimately, the Fusaka upgrade would have doubled the blob capacity, marking a pivotal move for the Ethereum ecosystem. Impact on the Ethereum Ecosystem Admittedly, the Ethereum ecosystem is expected to see more developers and users join the bandwagon. With the introduction of faster and cheaper transactions, developers and business owners can explore more efficient ways to build on the L1 blockchain. This means we can see initiatives like crypto payment solutions and more decentralized finance (DeFi) projects enter the Ethereum bandwagon. Users, on the other hand, will benefit as they execute cheaper on-chain transactions. Despite the benefits from this initiative, some in the crypto community worry about the reduction in Ethereum’s gwei (the smallest unit of the Ether coin). Shortly after the Dencun upgrade, Ethereum’s median gas fee dropped to 1.7 gwei. Fast-forward to the present, and the median gas fee sits at 0.41 gwei, according to public data on Dune. This drop hints at the drastic reduction in gas fees, which could affect those staking their crypto holdings on the L1 blockchain, making it less attractive to stakers. Since the Fusaka upgrade aims to reduce the L2 network gas fee further, some observers may worry that crypto stakers will receive fewer block rewards. Time will tell if the Ethereum development team will explore new incentives for those participating in staking. Will Ether’s Price Pump? There is no guarantee that Ether (ETH) will jump following Fusaka’s launch in December. This is because the second-largest cryptocurrency saw no significant price movement during past major upgrades. According to data from CoinMarketCap, ETH sold for approximately $4,400 at the time of writing. Notably, the coin saw its current all-time high (ATH) of $4,900 roughly a month ago. The price pump was fueled by consistent Ether acquisitions by exchange-traded fund (ETF) buyers and crypto treasury firms. Source: CoinMarketCap Although these upgrades do not guarantee a surge in ETH’s price, they have a lasting impact on the underlying Ethereum blockchain. Conclusion Over the past 10 years, the Ethereum network has had no rest as it constantly ships out new upgrades to make its mainnet more scalable. The Fusaka upgrade aims to make Ethereum layer-2 networks cheaper to use. To ensure its smooth usage, several testnets are lined up. Stay tuned for updates on how Ethereum will be post-Fusaka.
