Consulted again with my lawyer..what is written and what is actually done, as most people in argentina know, are two different things. He is telling me that IN PRACTICE, they don't revoke your permanent residency if you are out of the country for more than two years. His firm CURRENTLY has clients that have been living for years in China, Brasil,among other countries, who own properties here, and have been coming and renewing their old DNIs (book form) for the new ones without a problem.
There are plenty of laws that are on the books in the US and here that are antiquated and not enforced, or just not enforced. My immigration lawyer knows how to differentiate between what is actually being applied to what is on the books but never used. If he were such a quack I wouldn't be recieving my permanency now. I have had 0 problems along the way. His firm came recommended to me years ago by other expats who were here for their businesses. He tells it like it is, not out of context of the reality. Skepticism is ok, but referring to him as a quack seems way out of line!.
