What should I do if I need to exit Thailand to renew my passport while on a 90-day single entry Non-B visa?

Hello,

I am currently on a 90-day single entry non-b visa. However, during these 90 days, I will have to exit to my country and renew my passport (since it cannot be done from here).

The school where I work gave me this form to present to the immigration office 2 weeks before I exit Thailand.

I'm just here to ask if anyone has gone through a similar situation, and what was the outcome?

Thank you
