Ok well i am fairly certain i could get a company to sponsor me for a work visa here.
Edit: I shouldn't have any problems getting in if i get a work visa from this company before reentering i assume?
If you don't "get" the "work visa"
before you leave you, will not be able to get it until
after you reenter, unless the work visa can be granted by an Argentine consulate abroad...and I don't think that is possible.
You could leave and be certain of being able to reenter if you have a precaria, but you can only get that after you submit all of the required paperwork to migraciones, including the paperwork migraciones will require from the company (which must be approved to hire foreigners to do a job that cannot be done by an Argentine).
In other words, if you are able to submit all of the required paperwork before you leave and it is accepted by migraciones, you will receive a "precaria" which will allow you to reenter without any problem.
PS: In order to renew a "work visa" you'll have to provide the last two months pay stubs, so the company will have to be willing to pay you for the last two months if you plan to renew (even if you aren't really working for them and you give them back the money). They would also have to pay AFIP the appropriate taxes based on your salary and those funds would not be refunded by AFIP.
You are obviously aware of the consequences for being a pseudo tourist. It would be interesting to know the "consequences" (if any) for being a pseudo employee (as well as a pseudo employer). I'm "fairly certain" that lying to migraciones is a crime.
Hopefully, citygirl and/or Bajo_cero2 will have something to say about that.
