I am planning to travel from US to India, for which there is a Lufthansa flight that goes through Frankfurt. There I will be switching from one Lufthansa flight (Lufthansa 9053) to another (Lufthansa 758). The layover time in Frankfurt is around 2 hours.
I am an Indian citizen. I am on H1B visa with an approved extension (has the new I-90 form). But the visa has not been stamped yet in my passport. I would like to know if it is legal for me take that itinerary through Frankfurt (or) do I need a transit visa?
