I think if you use H-1B for your company you should be denied from using any tax breaks when filing US taxes.
The US is a nation of immigrants. As it stands now, H1-B is one of the few paths for technically-educated people to get lawful work and eventual permanent residence and citizenship in the US. I don't think there's anything wrong with sponsoring an H1-B for a talented and qualified person who wants to live in the US. There's room, and there are jobs, and complaining about immigrants is just stupid. That said, the H1-B…
The US is a nation full stop and we can write whatever laws we please without regard to when people arrived here in the first place.
Are Madagascar, Mauritius and Haiti also disallowed from having immigration restrictions because they were also populated in the Modern era?
