Question: how long do you have to stay in the us with a green card?
Answer: Information. I am a lawful permanent resident of the U.S., can I leave the U.S. multiple times and return? If you are a lawful permanent resident (green card holder), you may leave the U.S. multiple times and reenter, as long as you do not intend to stay outside the U.S. for 1 year or more.
