I am working in US on H1b visa. My visa stamp & I94 expired last year but I received my I797, which allows me to work legally in US. I only need the h1b stamping for reentry after leaving the country. I am planning to travel to Portugal (Lisbon) for my H1b stamping and return to US. I have a valid Schengen visa.
Do you think I will face any issues in boarding flight in US or after landing in Portugal because of my expired stamp? I have read stories where the airlines do not let you board a flight because you can't return to US. Ironically, that is exactly why I am travelling in the first place (for my stamping and thus return to US).
Appreciate all your feedback! This is my first post - happy to correct it if it doesn't meet the standard.
