The E-Visa process seems quite simple, but I have read that there are often problems with payment. Others have suggested that I apply for a visa upon arrival. These both have pros an cons, and I need more advice trying to narrow it all down. the E-visa process is not just the fact that others report that the payment alone can take up to a week, but the security of it. It seems safer to apply on arrival, but I worry of all the things that could go wrong. Any advice?
