Why is the Under Consideration Period for My Dependant Visa Extension Until December?

I was supposed to come today to immigration in Buengkan to get my remaining 11 months stamped in on a yearly extension based on marriage. My wife was in contact with them the last few days do to other things. The regional headquarters in Khon Kaen suddenly wanted an updated copy of my bankbook, again, even though I applied in September and haven't heard from them since. Buengkan office told her everything okay again, but they will call on a later date when I can come and get my stamp. They couldn't specify when exactly. Guess immigration all over the country is running busy these days due to obvious reasons.

Mine is taking 6 weeks instead of the usual 4 at kalasin

So you were applying for a year extension of stay based on raising a half thai child here correct?

Strange they'd give you an under consideration stamp dated until the 21st of Dec (that's a good ways out :O 53 days to be exact).

Year extensions based on marriage to a thai, raising half thai children typically get a 30 day under consideration period (not 14 days) but I got no reason why yours was so much longer..
