Can I enter Thailand as a tourist after my work permit ends?

If your work permit is cancel or not doesn't matter if your visa is single entry it is canceled when you leave. It's up to your company to cancel your work permit. Then you can re enter on visa exempt or whatever

Hi Natalie! From our experience assisting DTV applicants:

Yes, you can enter Thailand as a tourist on since your work visa would have expired before your return.

Many of our DTV applicants have followed a similar route.. cancelling, exiting and then re-entering on a tourist stamp before applying from a neighboring country.

We've successfully assisted over 110 applicants in the past 3 months with their DTV visa application so we are quite familiar with the process, feel free to ask anymore questions you have!

Yes you can enter as a tourist

If you are no longer working you should already have cancelled your work permit and associated extension of stay and left the country. Not cancelling it means you are on overstay
