BACKGROUND: My H1-B visa on my passport has expired but have a valid H1B approval notice that expires mid-May 2014. My company will start my H1-B extension soon (extension beyond the 6 year term as my labor application for green card has been filed). I need to go to Canada for a couple of weeks around end of April 2014.
QUESTIONS:I have the following questions:
1. Is it OK for me to travel to Canada and back with my expired H1-B visa and valid H1-B approval notice?
2. Does my travel to Canada have any effect on my H1-B extension application or my PERM labor application?
3. Any other document you think I should take with me to re-enter USA safely.
