Can I Transfer My Non-B Visa to My New Passport as a Philippine Passport Holder?

At Chaengwattana you need the following copies in addition to the "transfer stamps to a new passport" form which you can get out there

Take BOTH passports (and the letter from your embassy) to the immigration office with the documentation from your employer that uses the NEW passport number so you can get the Non-B visa notation added to your passport (it will say you got a Non-B visa in passport xxx on xxx date and entered the country on it on xxx) and then they will put the new extension inside the new passport.

Kind of bad timing that you didn't get a new passport BEFORE you got the Non-B visa :/ causing you to do all this extra work just before you get your extension.

As a teacher you mist have (had) single entry Non-B. Then it’s already used and no use anymore (means first about your Non-B visa sticker). You are currently entry from that Non-B. That’s admitted until stamp has to be transferred to your new passport.

Bring your both passport and letter from your embassy about new passport to immigration office and get it transferred. AFTER that apply your extension.

‘admitted until’ date of your new extension will be earlier one of same date to validation of your passport or 1 year or contract period.

If you apply extension first you will get only until June.

But in (rare) case you have multiple entry Non-B, it’d be different story.

A visa (as in the sticker in your passport) can’t be transferred. If you need to travel just use both passports. When you go to get the extension of stay this will be stamped into your new passport. Once done you don’t need to use your old passport for travel.
