Issue a Tourist (TR) multiple entry visa:

Hi everyone, my husband wishes to issue a tourist multiple entry visa (holds an Austrian passport). We are currently in Thailand and he is looking for an optional country to exist to:

1. In the Thai consulate website of Vietnam and Cambodia it didn't mention the option of multiple entry (only single) and we can't reach them- do you know if it's possible to issue a multiple there?

1. In the Singapore website it says application should be sent at least 2 weeks before entering Thailand- but my husband doesn't have the time and needs to issue it by this week (leaving probably tomorrow..)

We would appreciate your kind recommendations regarding the questions..

Thanks!
