Hi, I have a visa dilemma. I have already gained two 30 day visa stamps crossing the border by land and one 30 day visa stamp at an immigration office. And now I need to extend 20 days beyond my last visa end date. What can I do? I'm thinking of going to the immigration office and begging for one more visa stamp of 30 days. Is there any other alternative bar flying out and back in? Please help me!
