Frankly, I do not know the answer to your question. Actually I would be as interested as you in finding out.
Having said that, I think such a group should only advocate in issues that are specific to its membership, that is immigrants, such as the passports, social security treaties including double taxation, access / availablility of Spanish language classes, etc. I do NOT want Uruguay to become another USA, Canada, European Union. Quite the contrary !!!
I came to Uruguay because I truly like its people and see its governments as being respectful, friendly and service oriented when dealing with all the residents of Uruguay (yes, including us immigrants). I would not want to cause a change of attitude (by practicing a we against them mentality).Â
At the same time I think we could also share our experience with certain other issues in the countries we obviously left, in order that Uruguay can benefit from this experience and could avoid making these same mistakes. If this would be done on such a respectful basis, offering advice instead of coming across as know-it-alls or better Northern / Anglosaxon people I would support that too, something like a think tank made up of immigrants and non-immigrants interested in the bigger picture perhaps.
I hope this conversation will continue.
