Loei Immigration Retirement Extension

Good day, 

I am considering a move to the Phu Ruea area of Loei province and would like to inquire if anyone has direct experience with Loei Immigration

and more specifically obtaining an 'Extension for purposes of Retirement'. Do they have any unique rules, or similar that I should be aware of?

Currently, I have used the Udon office for my past 2 Extensions using the Income Method with no issues. I hope to continue using the Income Method this year, (though prepared to use the 800,000 bank method if needed). 

I will visit the Loei Immigration office next week to ask in person but would appreciate comments from those that have may direct knowledge regarding this Immigration office

Many Thanks!
