1st time: Non-O marriage visa

Hi everyone. My husband and I recently got married in Thailand and we now have our Thai marriage certificate. He is currently on a visa exemption, which will expire on 9 April. We’re planning to apply for a Non-O marriage visa for him, but so far no Thai bank (Bang Na area) has allowed him to open a bank account because they told us he needs a Non-O visa first.

1. Does anyone have any suggestions in our situation? Are there any banks in Bangkok or nearby that might allow him to open an account?

2. We are also planning a short trip to Laos for a few days. When he re-enters Thailand, will he receive a 30-day or 60-day visa exemption stamp?

Thank you in advance for any advice 🙏

Previously I went with an agency to Laos on my first ED visa. Now I need to go to Laos again.

Will going alone without the agency be any different?

I don't want to suffer the bus ride from bkk to laos again.

Any advice would be much appreciated
