I have relatives who run restaurants in America. Can I immigrate to America?

First of all, it depends on what scale restaurants your relatives open in the United States. This mainly depends on his tax returns. If the annual tax return is high and the restaurant is big, he can help you apply for a work visa. As for getting a green card in the United States, you have to continue working before you can apply. Your technology doesn't need to be recognized by others, as long as your relatives recognize it.
