I know from realtives' experience that getting a re-entry permit is not an easy breezy thing. They lived there for 2 years with GC and had to come back to nurse a dying parent and it was a PAIN getting it. And this is a guy that holds a key position in Microsoft, owns 2 houses and has a son that was born in the US. Point is, it's gonna be extremely hard to get such a permit for a 'newbie' immigrant who has zero ties to the US. They will see you have no true intention to live in the US (at least not in the near future) and your GC will be revoked. If you are sure you don't want to live in the US right after you get your visa (or in a few months period) then I wouldn't even go on with the process.
