I am trying to fill out the e-visa form for non o from London Embassy site. Everytime I attach passport and photo it says file too big and kicks me out. Anybody had same issue and does anyone know the solution

E visa Technical help if needed during online E visa application and you are experiencing any problems with file size upload etc

These are the telephone numbers you need to contact the London Thai Embassy. Note they are London times and you need to allow for BST.

Also note the extension numbers you will need to go through.

Direct lines are +44 207 225 5507 / +44 207 225 5524

Or +44 207 589 2944 / +44 207 225 5500 ext 5505, 5526

However, the staff are visa staff and they also help with technical issues.

It is better to call 1400 - 1700 hours. since in the morning the staff are providing services at the counter. Only if we are less busy, they can answer the phone in the morning.
