As the first SOF albeit non-regiment fellow to reply, I'm gonna give you some necessary tough love-
Here's the deal, do you want to be an Army Infantryman or not? The RIP selection rate is something like 20-30%, there's a whole lot of things that are keeping you from graduating other than your citizenship.
If you are intent on being a stellar Airborne Infantryman, then becoming a US citizen should be an easy secondary objective.
That being said, you'll get your shot at RIP after BAC, or down the road- it won't matter 10 years from now.
If you aren't interested in becoming a US citizen, I would recommend a different career field.
