You incorrectly quoted 7 days. It's not it's 24 hours.

@Joseph ****

, incorrect. Legally a TM30 must be submitted within 24 hours of declared arrival by the hotel, guesthouse owner or the housemaster. Saying that, in reality TM30 is not endorsed at this time.

Just turn up. It opens at 08:45 but people queue from 8am. They open the counters at 9am. Grab your queue ticket just through the door then sit in the right hand room, Thais go in the left. Your successful visa is issued the next day from 11am, remember to take the 'raffle ticket' they give you after you apply. Easy job.

@Dan *******

You need to bare in mind that Thailand is on full alert with criminals and terrorism, their systems work with Interpol. A lot of money has gone into developing immigration software. I understand you're being sceptical but the entry security is very high tech, I don't underestimate the progress of immigration, after all, it's in place for our own good and safety. Most definitely biometrics are part of the entry system.

I agree

but even new smartphones now have face recognition to unlock a phone. Trust me though they check biometrics on arrival. I know a Filipino who was denied entry for lack of funds, she returned home, got a new passport and picture done and attempted to re-enter but was cross matched with biometrics.

You may be linked by the biometric software on arrival. After you're asked to look at the camera the officer starts going through and scanning your passport. In the meantime the software has been doing a biometric check and will cross match your picture alone, no matter how many passports you have.

Hope I helped

I downloaded it from the Thai Embassy London website. Also try this link for most application forms
