Hey guys, im a local here so PM if you need any additional info.
For the guys trying to open a bank account...
Thing is, its really hard getting money in/out of poker sites with bank accounts, so here in argentina i use neteller (moneybookers is good too), having a bank acct is pretty useless imo
Argentina has restrictions to get USD OUT of the country (you will never/rarely have problems getting money in unless is an absurd amount that can be tagged as suspicious) so having money outside the country and just getting in what you actually use to live is by far your best option, if you are planning to invest here is a diff thing.
The best shot at playing on eurosites here is just using neteller/moneybookers and getting the card to withdraw/use as prepaid credit card.
Regarding visa, it depends on your actual country of origin so i recommend going thru this web
http://www.migraciones.gov.ar/accesi...es/?categorias
Goverment stuff is pretty flexible here, i woulnt go crazy on visa requierements since they dont go after illegal imigrants here as they do in most of your countries, and since most european/USA ppl are seen as tourist theres hardly any problems with them
Hope it helps
