My visa expires this November 6, 2019. I am leaving Thailand for 2 months the end of September. I have a non immigrant O visa multi-entry based on marriage from Savannakhet. I will re-apply for this visa in Savannakhet again. I will be traveling in and out of BKK airport on an international flight. So my feeling is to renew the visa before my trip to avoid some of the reported hassles coming into BKK visa exempt (I am American) but I also could just reapply when I return to Thailand. I will be traveling with my Thai wife. I am not sure it makes any difference but I depend on the forum for the good advice I always receive. Thanks.
