That's one of the reasons I was thinking. But why pay for my travel expenses for twice if they see that I'm undergraduate at first glance?

Why not. It's not like HR/given department pays for your trips out of their salaries. They just want to have the headcount for an interview.

Edit: From the people around me, and the companies I've been, big companies like that will discriminate you on age far less than not having a university diploma / other academic accomplishment. Finish that degree as fast as you can.
