> Some people get upset that someone on a 'non-immigrant' 'temporary employment' visa can apply for permanent residency, although that is allowed by the H1-B program.
The H1B visa is explicitly a dual intent visa.
https://en.m.wikipedia.org/wiki/Dual_intent
Becoming a permanent resident is explicitly allowed under the H1B visa. By contrast, if an immigration officer even had a suspicion that you intended to immigrate on any other visa, that would be sufficient grounds for them to disallow you from entering the country.
Further, the dual intent nature of the H1B visa means H1B employees pay social security and Medicare, even though they themselves are not eligible for it. Something you don’t have to do if you earn money on a non dual intent visa.
The H1B visa is indeed temporary. It lasts only 6 years. But it allows you, or your employer, to apply for your permanent residency on the basis of other categories while you’re in the U.S. on an H1B visa. IOW, the only real use of the H1B is that it lets an employer get to know an employee well enough that they’re willing to sponsor their permanent residency.
Also, the other reason the H1B appears overused and not “temporary” is because in a moment of brilliance Congress wrote laws so that there were an equal number of green cards handed out to people from Jamaica as those from China. As a result, when Indians and Chinese apply and get approved for a green card, they need to wait decades to actually get those green cards, whereas someone from Greece would get it instantly.
Since Congress hasn’t been able to write new immigration laws in 3 decades, extending thenH1B visa is the only way to allow folks who have essentially approved green cards to remain in the U.S., because they’re discriminated by their country of birth.
