Is your priority just getting a job that protects you from the instability in Argentina, or is your priority being an independent business?
I ask this because one option you can consider if the priority is getting somewhat stable money is sub-contract work.
In my case I'm working with a factory from South America. Currently our firmware studio is being expanded as an important client is scaling operations and there's a significant amount of vacant positions that given the client profile should be decently stable. Some of the guys from the company work from Argentina; some of them as direct employees and others as contractors.
English level could be a limitation for any of the options you consider, anglos will generally not like it if your English proficiency is below B2. B1 does not make it so nobody hires you, but they will sure expect you compensate that weakness with evidence of technical proficiency. Some companies like the one I'm working for at the moment offer benefits like English lessons, which could be of use if you decide to go with the subcontractor route.
