I used mexico bariatric center, and had dr, cabrera and valenzula. Surgery at mi doctor. I stayed at the marriot the nights I wasn't in the hospital..sooo nice! I flew home on the 6th day. I didn't have a passport, just my id and birth certificate and was fine. What you need to do is decide on what company and doctor you want to go through. I think there is 4 or 5 , mexico bariatric center, ready 4 change, a lighter me are a few. You will have a coordinator that helps you through ever step of the process. Just make sure you go to a hospital,not a clinic! I would go back to mexico for any surgery.
