I just immigrated to Hawaii for a month, and now I am going to study in California. I haven't got my green card yet. How can I modify the address where I send my green card?

Modify the delivery address of the green card:

1 The website of the Immigration Bureau directly changed to :https://egov.uscis.gov/crisgwi/go? . action =coa. clause

2 the old way, fill in the form AR- 1 1 and send it to the government: http://www.uscis.gov/files/form/ar-11.pdf.

Without a green card, you can travel to and from China; The problem is that you can't go back and forth to America.

Don't leave until you get a green card, or you'll be in trouble if you don't get a green card.
