Hello

I am F1 - OPT student. I have around 93 days left on my OPT. My employer just started documentation process for H1B. I want to visit Canada for couple days this week end (March 15 to March 17). Is there any risk associate regarding Re entry in USA. I will going by Bus. I see some post on social media about F1 student who will be beneficiary of petition to change status to H1B in this year 's H1-B cap gap face problem? Again I just started my documentation process.
