Hello, Linda!
We are presently going through the process. So far it worked very well for us. Just one and a half months after arrival we now have or 2 year permit, public health insurance, a bank account and a car. As a matter of fact we had all but the car after less than three weeks.  Although I normally do all administrative things myself, this time I splurged and hired an immigration lawyer, since I do not speak Spanish, and they really have shepherded us through all steps. If you would like more information please private message me.
Good luck!
Armin
P.S.: Now we only have to find this elusive property to call home. There are very good realtors in Uruguay and also those that would not have survived six months in the USA
