Hello, Todd,
I have a Non-O (based on retirement) Multiple Entry.
I went to Myanmar for a few days (Ocktoberfest) and upon returning, the Immigration Officer at DMK added a stamp to my TM6 and on the entry stamp as well.
NON-RE
My VISA Expire date is still the same, Jul 2019.
Have you heard of this before?
(this was my first exit/return since getting the VISA, and Multiple Entry)
Thanks.
