thanks for advice, I was also wondering why immigration at BKK didn't mention something but that might be due I was leaving the country long time before visa exempts ever expired
exactly same I do in case of insurance... I can put my mandatory German public health insurance on hold for 70€/month when longer absence from EU (as I am 'covered' in EU) than 3months continuously so I can spend that big amount of money (500€/month) on my own decisions and insurance coverage for SEA.
