那到時我怎麽證明我在美國呆滿了一年？
-It is staying outside US for one year. When you leave US, you need to provide the I-94 card to the airlines (USCIS), then USCIS will know your leaving. Whne you come back, USCIS will have your new record.
呆滿一年是呆滿整的一年還是可以分段加起來呆滿一年？
-You can make a short break such as less than one month by entering US during the year and 可以分段加起來呆滿一年. If you enter US and stay too long, you have to recount it again (not)可以分段加起來呆滿一年. This depends on USCIS judgement.
