I am from the U.S. and I'm here on a 2yr TWP valid until Sep 2010, my husband is from Mexico and he has an open work permit valid until the same date as mine. I want to apply to extend my stay. Does my husband need to get a 2nd medical exam to be able to extend his open work permit? He arrived before the new law came into effect on the new visa requirement for Mexico, so now he will have to apply for a visa if we want to go on Vacation, which is not a problem. But just want to know about the medical exam. I did apply for PR last March 2008, still waiting for initial assesment. I know that just by getting another extended work permit doesn't guarantee our re-entry but i have to try. My daughter is turning 15 this month and we are going to have her quincenera in mexico (debutant ball) next summer, i have to go to mexico on vacation next summer and want to get all my ducks in a row before i go.
