Will an Invitation Letter Addressed to the Kuala Lumpur Consulate Cause Issues for My 90-Day Business Visa in Penang?

@Ly ************

, you;re mixing up terminology and that's causing problems with the answers you're getting.

You EXTEND visas at the immigration offices inside the country. and at a thai consulate in another country you get a NEW visa entirely.

SO what you're wanting to do is BUY another 90 day single entry Non-B visa from the thai consulate in Penang.

What is the reason that the invitation letter is addressed to the consulate in Kuala Lumpur and not where you want to go apply for the visa?

AFAIK: the documentation has to be addressed to the consulate you're applying at ..

Yes, you can not extend a visa in Penang or in Kuala Lumpur.

You can apply for a new visa.

The letter must be addressed to that Consulate, so you need to go to Kuala Lumpur or get a new letter.

Yes it will be change it to penang and can not be 3 month old

Probably so. Suggest you get new letter.
