How soon can I start applying for a green card after I get an American work visa?

First of all, you don't have to have a work visa to apply for a green card. The nature of green card is completely different from H1B. Having H 1B does not mean that you can get a green card smoothly. So in other words, the green card is actually when you are ready to apply.

Secondly, under normal circumstances, American companies will guarantee applicants to apply to the US Immigration Service for a green card after H- 1B visa holders have worked for them 1 years. After holding the H- 1B visa, the applicant can apply for a green card while working.

H- 1B visa is valid for 6 years. The new H- 1B visa is initially valid for 3 years and can be renewed. The longest initial renewal is 2 years, and the final renewal is 1 year, not exceeding 6 years. Six years is enough time for applicants to apply for a green card in the United States. Green card holders can apply for American citizenship after living in the United States for a certain period of time. Few people directly become American citizens without getting a green card first.
