How can I manage the document requirements for a single-entry tourist visa to Thailand while I wait for my non-B visa processing?

Greetings,

I am from EURO, Italy.

I am supposed to go to Laos by land at the end of this month (2nd exempt visa expires on the 30th) to apply for a single-entry tourist visa. This is the first time applying for a tourist visa at a Thai embassy in a neighboring country.

As I am, currently, applying for a teaching position at a school in BKK, but I need more time for them to process my docs for a non-B visa, etc.; how can I manage the documents required for the 'single-entry' tourist visa knowing that I will continue staying in Thailand?!

5. Travel itinerary to and from Thailand and accommodation e.g. plane/train/bus ticket, hotel booking, letter from whom you will be staying with and a signed copy of his/her ID

How did you guys manage point no. 5?

Also, the trip from BKK to Laos, accommodation, etc

If there is anyone who has any recent personal experience, please, message me in Messenger.

Otherwise, if it is too much of a hassle to get through it by myself, I may have to opt to travel there with a visa company.

Any help will be greatly appreciated.

Cheers
