May I ask a specific question about the 60-day, tourist, e-visa, proof of onward travel when planning a 30-day extension? What kind of onward-travel proof will be required, assuming it must be within 60 days and I know I will not use it? Should I get a fully refundable airfare and cancel after the visa is issued? Can I buy an inexpensive bus ticket and forfeit it? I searched for this topic but did not find a post directly on point. Thanks to all the contributors here who share their knowledge.
