What type of visa will my husband and I receive in Vientiane, and how do we handle renewals and extensions?

Hello All❣️

I just want to make sure I know what I am getting in to with my new visa.

I am going to Vientiane to get a Non-B (English teacher US Passport) and my husband will get a Non-O (based on marriage to me US Passport)

What I want to confirm is:

1.

Will we both receive a 90 day visa (similar to the Education visa) that we have to extend at immigration in Chiang Mai every 90 days up to 1 year

Or

Will we receive a 1 year visa (that requires 90 check ins at immigration)

2.

My second question is at the end of 1 year of having the visa do we need to leave the country for a new one or can we receive a new visa in Chiang Mai (as long as I still work for the same school)

Thank you in advance ❣️
