I was in similar situation only my baby is coming in 3 weeks. I used the amnesty period to get everything ready. Got my extension last week. Got rid of a lot of worries. Good luck!
Interesting. I was just at Korat immigration today to look at my options for the future. The IO told me that if I went with a one year extension based on retirement/over 50, I could take the money out the next day after I got the stamp if I wanted to as long as it was back in 2 months before the next extension was due. Didn’t sound right to me. Do they actually check afterwards?
