Earlier quoted context omitted.
Has to do with H1b visas. Post layoff, a person on H1B has 2 months to sign a new job offer or they must leave the country. Majority of Indian and Chinese H1bs do not have green cards, and are the main group that suffers. Some of these folks are well into their 30s, with kids and houses in the US.
I'm kind of curious how they have houses in the US. I'm from Europe but I would have kind of assumed that banks aren't willing to lend to someone without residency pinned down or would only do so at extortionate rates. I also kind of assume most wouldn't be able to pay for a house outright.
If you pay your monthly installments and have solid financial health (good credit score, high income, paid your taxes) then you'll get a standard deal. H1b Indians are on 30-50 yr queues for green card. Buying houses without residency is the norm, not the exception.
