Hi, I am about to apply for adjustment of status (F-1, got married). In connection with that I intend to submit form I-131, since I intend to travel to Germany sometime next year. Since I do not have a special date in mind, and I am not even sure if I will travel at all, I wonder how to proceed.
What happens if submit I-131 and dont travel after all?
What if I enter on date for travel and travel actually at another date?
If I dont submit I-131, how long am I stuck here until I can travel freely again? (I cant affort to pay another 350 buck just for this form)

Many thanks!

What happens if submit I-131 and dont travel after all? Nothing.

What if I enter on date for travel and travel actually at another date? Thats fine.

If I dont submit I-131, how long am I stuck here until I can travel freely again? (I cant affort to pay another 350 buck just for this form) Considering that the I-131 form is free and bundled with the $1,000 or so for your I-485, it makes no sense not to file it.
