Some people tell me that i do not need a re-entry permit since i am travelling for less than one year. Others say that I must have one to reenter the U.S. I am really confused about whether i should buy one or one. I am going to travel out of the U.S. for about 1 and a half month. Could anyone who is an expert in this tell me whether i should buy reentry permit or not? I really appreciate your help and consideration.
Sincerely,
Phu
