Why Did My Non-O Marriage Visa Extension Only Get Approved for One Month?

Hello,

My non-O marriage single entry expired 2 months ago.

I went to apply for 1-year extension with my Thai husband today.

All documents submitted, 1900 baht fee paid. No extra fee required.

I got a 1 month extension instead of 1-year. It is said to be under consideration and I gotta come back next month.

My questions are:

1. Does it happen like this to all first timer?

2. What should I expect in the next meeting? What are the possible outcomes for my extension application.

Thank you for your advice :)
