求助签证过期！！！

noahark4

签证一年期限，5月过期。来美读书一年了，I-20期限是4年。6,7,8月去第三国实习，能拿旅行签证过去吗？过了后能回美国吗？若回不去，能回中国吗。回到中国能续签能成功吗？
谢谢

once you arrive the US, it is easy for you to apply to renew it. However, you need to apply for a new F1 student visa once you leave the country except Canada. Depends on where is your third country, it is very easy if the third country is a NATO member.Good Luck.
