I would like to ask if there are any differences or bigger/smaller difficulties when applying for Non-Immigrant B visa (as MD of a new company in Thailand) in following embassies: Hanoi, Phnom Phen, Penang and Vientiane. Could anyone, from their personal experience, either recommend or not which would be the easiest one? Or are they all the same in case I will have all the required documents? Thank you for advice!
