Recently we have learned that it is again possible to extend certain short term visas in Myanmar. Specifically, if you have one of the following visas:
1) EV Meditation Visa
2) Entry Visa
3) Gratis Visa
these may be changed to a regular meditation visa once inside Myanmar.
Please note that this does NOT apply to Tourist visas, which cannot be extended.
Also, one may obtain a regular meditation visa directly in Singapore by applying at the Myanmar embassy there, in person. This news was passed to us by our good friends in Yangon, Zaya & Mrs. Yip.
