Hi @calvin22a
I’d like to answer your questions in english because it’s your native tongue and probably would be easier for you or another english reader of this forum to use this as reference.
Ofc my english isn’t my native tongue but i’ll try to do my best for you, i just consider this necessary.
About study
The first thing that you want to do is to reach a master (maestría en psicología educacional en UBA) so probably you’ll need information about the docs that you need to present to the university right?
In this case, you should talk with the faculty of the UBA directly (here’s their contact info) and you could find interesting their requirements to apply:
maestrias@psi.uba.ar
maestriapsieducacional@psi.uba.ar
You must consider translate your study certifications (degrees) with a “Escribano Público Certificado”, take that in mind, usually they ask for it and “Apostilla de la HAYA” (don’t know if apply to U.S).
About traveling, living and working
Travel
Yes, you have 90 as tourist, don’t forget to get your passport stamped properly when traveling, pay the respective tax for leaving U. S. A. to Argentina (isn’t too much, mb 20 bucks) buy your flying ticket with depart and return (it doesn’t matter if you lost the return ticket).
You could check this video too:
I think you’ll understand but if needed I’ll put subtitles on it (ENG ofc).
The requirements to travel to Argentina are also here in the official page of Migraciones Argentina as far as I know you do not need Visa.
Documentation
Now to live, work, study and enter or leave the country for two years you could process paperwork for Residencia Temporaria, remember that you aren’t a MERCOSUR member, so you’re “NO-MERCOSUR” and they’ll ask you as requirement for this process an university inscription (recognized by Migraciones like the UBA is) or a pre-contract to work with a company here.
After you have lived your first two years here, you could get the Residencia Permanente for 16 years more.
Working as English teacher could be a good idea, I’ve seen a lot of particular teachers (maybe you could teach me n_n), you couldn’t work legally until you get your documentation(Residencia Temporaria) and probably your degrees certified by the Ministerio de Educación like this process.
You can work with your documentation in order, there’s no such law or at least I haven’t heard something like that.
I’d wrote an article that you’ll found interesting about where to live in Buenos Aires.
If you need a place to stay a few days or maybe months consider this hostel in San Telmo, it’s really nice and you’ll get 5% disscount by mentioning this website.
I’m glad that you’ve found us, excuse my bad english skills and I hope you find this useful, your spanish is really good.
Ask everything you want to, I’ll be glad to help.
Regards.
