Hello, I am on an Education visa which runs out in March. I want to apply for the DTV in January. Do I need to cancel Ed visa before I leave or can I cancel on my return with the DTV. I will apply in Cambodia but my flight is early Monday and immigration is closed over the weekend. I'm concerned that the DTV will not be successful as I have not officially cancelled it at immigration and I only have an exit stamp as you can't have two visas at the same time. Any advice would be welcome.
Thank you.
