Anyone know of an agent in Laos for help with Thailand Non-immigration B (business) visa for UK citizen?

Does anyone know the requirements for applying for a non immigration b (business) visa from a neighbouring country such as Cambodia? I’m a British citizen.

The requirements from UK are as Follows:

1. Recent photo 2. Passport page. UK bank statements. 3. UK proof of address. 4. Letter from company

Peace upon you. I would like to know that once my work visa expires, can I stay in Thailand for about a month more on tourist visa? How do I change my visa , which is Non Immigration B, to a 3 month tourist visa? Any insights are appreciated. Thanks alot in advance.

Hello all.

Can you point me in the right direction please?

I am changing from a 60 day extension visa (cannot leave due to covid) to a non immigration B visa.

My son is changing to an education visa.

My husband will change to a guardian visa.

Can the 60 day covid extension visa be changed to another type while in/ without leaving the country?

Thanks.

Rachel.
