I wish that Argentina was reciprocal with the United States for residency. When I married here in 1983 it took my Argentine wife a wait of two weeks for the United States Embassy to issue her a permanent residence visa. When she arrived at the airport in Miami they said "welcome to the United States" and mailed her "green card" to our home in a week.
Not so for my residency in Argentina. First I had to get an immigration attorney to apply for residency through the Argentine Consulate in Houston. The consulate after a few weeks called and stamped a "Residente Permanente" visa in my passport. On arrival back in Ezieza they still only allowed me 90 days until I picked up my DNI. I had to bring copies of my birth certificate translated, notarized, apositled along with a letter from the Houston chief of police stating that I had no record. Then a visit to our local police station in Buenos Aires where I spent a day to get my finger prints. I took this to immigration along with our marriage certificate and other forms to the Immigration office in Antartida Argentina, Buenos Aires where they issued me a receipt as a temporary DNI. They said they would have the card ready in about two weeks. When I returned with the receipt they hesitated and then said that it was lost "en tramite". It is still lost. When I most recently arrived about two weeks ago they let me come in as a permanent resident without reciprocity fee, but it took me a long wait while they looked up the law that admitted me. On leaving two days ago it was even a longer wait while I was lectured that the next visit I must re-submit all the paperwork, original copies, that they lost.
Talk about recipricity! My wife became a legal resident in three weeks with a social security card, work permit, drivers license. I have been working on getting Argentine residency for 31 years now, but have little to show for the effort, but have spent thousands of dollars in the process.
