For whom ever this may be helpful.

Birth Certificate stamp AFTER it has been translated from Thai to English.

Went to The Department of Consular Affairs in CW. The process is as follows.

Step one: Fill in attached form.

Step two: Take your documents to the "check your documents" counter. This is where you get your Q number.

A copy of every page in my passport was required (with or without the stamp it didn't matter). Original translation and copy of Thai birth certificate.

Step three: Wait for your q number to be called and pay.

PS: Note the different services available.

Feel free to ask any questions here. So the information can be in one place.
