1、我持移民簽證來美後,在還沒有取得綠卡的時候能否去加拿大旅遊?
2、由於我現在國內仍然還有工作要做,6.20來美後,9月上旬需要回國,明年2月初再來美,然後住兩個月後再回國住兩個月,這樣每年回國兩次(春季和秋季),是否需要申請回美證呢?
3、聽說回美證隻有兩年有效期,且隻能辦兩次,是這樣的嗎?-No law limits that, but if you apply for more than twice continuously, USCIS may not approve it unless you have very strong reaqson, e.g. you work for a US employer and the employer send you to work in China.
謝謝!
