What should I do if I can only upload one flight document for my Thailand multi-entry e-visa application?

I used the photo editor on my phone, and selected "collage" you can put two or more photos of your documents into one photo, and upload that, it was accepted for me on the Thai e-visa website.

I used imagine editing software to make all my images into one image. I included a note explaining I was traveling around so my inbound flight is from some place other than my home country. It seemed to work. But if they've threatened you to "get it right" I would try to contact them directly by phone.

Mary Clerk...you don't say if you are over 50 y/o or under. If over 50 you can apply for a multi-entry OA retirement visa in Australia or your home country or for a multi-entry visa in Thailand or as a single entry In both cases you will have to prove you have Bt800,000 either in Australia for the OA or in Thailand for the O visa multi-entry.

If under 50 y/o it seems you may be able to arrive visa exempt 2 times a year (maybe more who knows TIT) and leave each time after 3 months. I think this is clear now Hmmm maybe. TIT. With the taxation issue still unclear this may be a good option. For unclear tax reasons make your total stay 179 days p/y. The visa exemption is what I have already used for the 1 month with the one-month extension, it is quite simple and Thai immigration at Blupoint (no "e") Shopping Mall Hua Hin is very polite and helpful.

If you get a multi-entry retirement visa from either source for one year you can come and go as often as you like, But not on an extension if you get one....good luck, sweet travel. If you leave Thailand on an extension that's it the visa is concluded.

Send them by email

Send them a Email with the Information they require, that's what I did

One of two options

1) use a pdf editor ( easily find with Google) to combine the files into one.

2) use the 60 day visa exempt entry with 30 day extension

60 day visa exempt on arrival in Thailand with 30 day extension at local immigration office

Do as Brandon says but look your ´binder´ is not over the max. Mb you can upload.

Go online to find a site where you can add multiple PDF files to create one file

When i applied for my 60 day tourist visa i only sent my flight there & it was accepted

Use an online tool to combine all of your documents into a single one that you can upload.
