H1b visa stamping in canada in next 2 months in 2014

Hello Everyone.

can someone please suggest me on this matter.

i came in USA in 2008 on F1(student)visa but i did not completed my masters from USA as i already had a master of commerce from india.That is why i applied for an H1B and i got my visa approved then i have renewed them in November-2012 and now i am going to canada for my visa stamping and i have direct employer.

can you please suggest me about the risk?

should i go for stamping or i should stay in USA?

any aswer will be greatly appreciated.

why do u want to go for stamping?
