Does anyone know what will happen. I got my passport yesterday, after applying for 1 year visa extension and It's approved by chaengwattana immigration but they forgot to stamp the date for the next 90 days report. I don't know when I should to show up. My Non-b will expire 12 Dec, they let me come back 12 Dec to finalize my application for transferring my non-b to 1 year. 12 Dec the chaengwattana immigration took my passport for thoroughly checking and said that I should be back on Friday and they will stamp my passport for extending it to 15 Dec then I can get my passport. They did stamp my passport 15 Dec 2017 and another stamp Expiration date for one year 6 December 2018. I'm so confused because the HR Manager who runs everything says I overstay, but anyway I will go to chaengwattana tomorrow to put some answers into this one and I still need some advice
