Thanks

@Stuart ********

Thank you all for the replies. It really helps. As we haven't chosen a school we wanted to look at several before deciding (need to be there). Could another possibility be, apply for the STV for all of us which gives up to 270 days in Thailand and while there enrol in (chosen) school and start the guardian visa process? After 270 days hopefully, borders are open and the Guardian visa could be planned and applied for, a border run is done and Guardian visa activated?
