Thanks for the tips all! Fortunately, I speak English, Spanish and French fluently so all that is left is... well, pretty much everything else, like knowing how to be a nurse.
Knowing myself, I'm not ready or willing to do a four-year undergraduate program right now, which is why I was interested in completing an ASN. However, I spent a couple of hours looking at job offerings and you're right, it appears that very few facilities (if any) in MA hire ASNs. I'm sure that even fewer employers will be accepting that level of degree in two years time.
I've concluded that I will wait until I'm 24 and then enroll in an accelerated BSN program for adults at Simmons, which provides scholarships and is better suited for someone who doesn't want to take a traditional path. Their clinical placements seem amazing (they're certainly better than anything BHCC could offer me) so I think it will pay off to wait. For now, I'll continue traveling
Anyways, I appreciate the words of encouragement and NGO recommendations! Thanks all.
