8老師，
我們是加拿大公民，但住在美國，申請F1簽證時，要遞交Form I-901和繳費，想問一下，Form中的Address可以是美國的地址嗎？
-Yes.
還是必須是國外的地址？
-Not have to.
這個地址是幹什麽用的？是要給我們寄Receipt嗎？
-Yes before, not now. You have to have a address, right? You will get the receipt immediately after you file I-901 and pay the fee online. Print it out and bring it with you when you enter US.
By the way, are you currently an F-1 student (i.e. are you studying at the school now)? If yes, you don't need to file I-901 and not need to pay the fee.

我們周末要回國，那還來得及嗎？我看網上說在網上Check Status，能不能從網上打印出Confirmation？
-Yes. See:

我們回來入關時，申請F1簽證，除了護照，I20，是不是還要這個Receipt？還有其他的嗎？
--Because you are Canadain citizen, you don't need to get the F-1 visa stamp in the US Consulate. You just need to bring your passport and the I-20 to enter US, and you will get the F-1 I-94 (i.e. F-1 status) at the port of entry. If you are a new student, you also need to bring the I-901 filing receipt (i.e. the SEVIS fee receipt) with you.
Talk to your school before you leave US.
