If you apply as business owner ( like myself ) you will need to show your company’s real activities and of course the easiest way for me is to show proof (information and pictures) of 2-3 clients. So if I were you I would provide information of clients/ distributeurs outside of Thailand.
Keep in mind that their job is to make sure that you have enough income/money to spend in Thailand. And embassy officers are not customs or police :-)
For flight ticket at airline counter when u check in normally they require return ticket along with your visa
Of course u are not sure of the return date I can set you free with this ( only 10$ fee)
We just buy you one way ticket , I will issue separately the return ticket the day of your departure to check in ( after check in and enter country I cancel this return ticket as travel agent I can cancel ticket same day without charge )
Then when your DTV is approved you just buy new ticket ( free of mind , free of change fee …)
If u are going to one country in order to apply for DTV and of course you are not sure about the return date. I can make this problem away by offering the return ticket with fee of 10$ ( as an agent I can cancel ticket issued the same day without charge ). With this return ticket you can check in and enter the country without any issue once you enter the country I will cancel this ticket
Visa rejection doesn’t affect your visa exemption. Your arrival with Visa exemption is on the hands of immigration officers based on your history in and out the kingdom. If you already do more than 3 times visa run in a year for exemple they will have questions …
It depends on your situation there are many points to consider :
1) Thai Embassy in Indonesia and Malaysia seem little bit easier to approve than others ( just my opinion)
2) Have u ever visited any country neighbour ? You need at least 7-10 days in the country so why take this chance to visit the country that you always want to visit.
3) in term of travel cost: Vietnam, Cambodia , Laos and Malaysia are the economic options
There is not best country but you have to choose the suitable one for yourself
There are many cheap flights from Bkk to Vietnam : Hanoi , HCM , da nang … specially Phu Quoc Island where u have visa exemption for many countries. Otherwise you may need evisa ( it takes 5-7 working to apply ) and living costs are quite similar to Thailand
