Question need to be solved
Hello,
I am an International student in Canada,I am carrying chinese passport.I got my American travel Visa last year in Vancouver,and it will be expired on the 29th of Jun.I'll be attending a conference in Orlando on the 24th of Jun,and the conference will be end on the 27th,but my buddies and I decided to stay in Florida and have fun for a little be longer,maybe we will be back to Canada at the begining of July.Since my Visa will be expired,I am kinda worried about that,some of my friend told me it should be ok,because the expire date on my visa means the last date I am allowed to entry in States.
So the Question is:Will it be Ok for me to stay in Sates for a little be longer than my expired date showed on my travel VISA.What if it is not allowed,and I stay in States for probably 3 days longer,what will happen to me?

答案

i think it's nothing serious.
for best .you need to apply the delay of visa
