What is the process and duration for obtaining an ED visa in Laos, and can I use baht during my visit?

The process for obtaining an ED visa in Laos typically takes about 1-2 days, rather than 5 as you mentioned. It involves dropping off the application at the consular section and picking it up the following day. Make sure to have the correct visa application form and the required documents from your school, as these are crucial. Be cautious of scams around the consulate building, as some may try to offer unnecessary services. For your travel, you can take a minibus from Udon Thani to the Friendship Bridge, which costs around 150 baht. In Laos, you can indeed use Thai baht in some places like hotels and restaurants.
