Her present "tourist visa" expires on April 2. She came in from Singapore on Feb. 3 and received 30 days. Then she went to immigration here and received 30 more days.
No more extensions possible in country.
Have you heard of any immigration offices in country granting some kind of "special" extensions. I seriously doubt it. They would have no motivation to do it. My guess is they would simply say, "Go back to your passport country. Get out of here." :-(
