Thanks for the reply, I was hoping you would pen something back.
Ok, more details - she never over stayed and since getting married has been on a 2 yr greencard since 2006. She is currently having to go to the 'delightful' immigration office to get extensions - 1yr automatic, then 3 months, 2 months etc....
The possession wasn't pursued to a conviction due to pre-trial intervention in which she was required to help the police ensnare a know drug dealer. She was also given some community work. It is noted that no conviction stands. (is there a case for the clemency office on this matter do you think??)
She fully intends to leave the US, the only concern is whether to appeal the greencard if its denied in order to be able to visit family (her mum is very old now) if she has no other options. If she can fall back into visa / visa waiver circs then all is well.
