What are the requirements and recommendations for extending a Non-O visa for my Pakistani husband in Thailand?

(just sharing our experience to immigration office how disappointed I'm from my government the way they treated foreigner)

I went to immigration office chaing wattana on 11 Nov after my quarantine no one told me about my husband TM 30 document ( i didn't have any idea about required document that's why i went there) but no one inform me about anything and said your husband visa is expiring in January and bring the following statements gave me list of non O visa requirement.

I prepared all document except bank account as we couldn't fullfil it as we don't have saving of 0 baht to show.

Yesterday:

Outside information recommend me to do covid extension than wife visit than child visit after that if you still couldn't complete bank statement than your husband has to go out of country i said okie they gave me application form, filled and took que

After a long wait.. the inside staff told me it's already non O why do u want covid extension !

2nd document was do you have TM 30 i said i have no idea about this document

3rd they ask for criminal record and gave me letter to go to police headquarter near Siam paragon but before that ask me to get TM 30

They ask us to go to muangthong Thani register foreign residence thing I went there and the officer there were terrible

When I present the document they said why are you coming today it's being almost 3 month I told him my situation that I didn't knew about it he said you have to pay fine 800 baht I said from where am I supposed to know all the law and requirements as I'm pragnant I can't travel that much from one end of of Bangkok to another

He get up and said if you want to do it than pay if not than don't waste my time and went outside

I was sitting there confuse (what did I said wrong )

Than he came back with (sorry I went to poop )

Thats how immigration staff are

We went to police headquarter almost close by 330pm the staff were nice talk very politely and did everything for us but the results going to take a week and Totally understand but I didn't saw any requirement of criminal record on the paper they gave me.

I told them if you give 2 month extension to my husband but for the next extension as it's almost near to my due date and I was not able to come than what is your recommendation (they said no for extension of non O husband and wife should come together as you have to take a picture )
