Greetings. I am a Canadian citizen still on year 1 of my first H1B visa. I understand that I do not require visa stamping to travel back and forth between the US and Canada (I have already done so twice) but I am unclear regarding the procedures if I take a trip to Europe or Asia. Is this a difficult or risky proposition? If it matters, my case was a change of status from TN to H1B so I didn't need to leave and reenter the US in H1B status. Any thoughts or information would truly be appreciated.
