Would I need citizenship to live in the States for 3-5 months coming from Canada? this isn't for now but in the future and i have no idea how and what?
My sister is in the Cali for University. The documents you must have are:your green card, visa (not the credit card I don't think) and passport. Therefore, I don't believe you need citizenship.
If illegal Mexicans can come over to US left and right Canadians shouldn't even have to worry about visas and all that bullshit. Shit, just come here and request welfare as a refugee and ski for a couple of years.
