Great article, well written. I'd certainly consider interviewing this guy - if I was hiring. Based on the other comments it's worth noting a few things:
1. Ahmed seems to be in the UK, not the USA. H1Bs don't affect him. This isn't obvious because he talks about the USA. However, the mass immigration into the UK might have impacted him by saturating the low skill markets such that everyone else has to fight over the remaining high skill jobs.
2. His internships and projects have all been ML/AI, with his most recent at DeepMind. It's not obvious from the article that he's been one of the people working on automating everyone else out of a job; an ironic twist given his predicament (I'm sympathetic but to some extent, those of us who live by the sword...)
3. The British economy is in the toilet at the moment. This is the most likely reason he can't find a job but it doesn't get a mention at all, which is curious. It doesn't make much economic sense to grow a corporate presence in the UK currently given that Labour is raising taxes, attacking the private sector, imposing heavy regulation on the tech industry and so on.
