Is a reentry permit a document that can be obtained by filing the I-131 form, or how can one obtain such a permit?

Could you spell out what "2 years at a stretch and generally up to 5 total without issue" means for non-native speakers?

That's right, the application is submitted using Form I-131. At a stretch here means a 2 year absence from the U.S. (without traveling back to the U.S.) and 5 year total means you could live abroad for 5 years without losing your green card (by getting reentry permits which can be issued for a total of 5 years).

Great, thank you
