I have had a yearly multiple entry Non-B business visa for many years now from the Hong Kong Thai consulate (where I am a permanent resident). Normally, I don't apply for a new one until the previous one has expired, but this year, the timing is off because I will be back in Hong Kong only until a week before my current Non-B expires, then will come back to Thailand (where I will be granted a 90 day stay) but then I am traveling from Thailand to Europe shortly after, then would like to return to Thailand without going through Hong Kong. This means I can't apply for a new yearly multiple entry Non-B visa (e-visa) from the HK consulate for my return to Thailand. Does anyone know if I need to actually wait until my current visa expires before I am allowed to apply for a new one? I tried contacting the consulate but there's no reply.
I can't get an extension of stay w/re-entry permit on a Non-B instead, because the frequency that I travel back and forth doesn't allow me to remain in Thailand long enough to process it.
