Thnks for your prompt reply the landlord is what you might call 'Slightly unhelpful'!! She said she needs the room vacated on the 4th.... If i went to BKK immi and said i no longer live in Chiang Rai and i have new TM30 for my BKK residence could the Ext i applied for in Chiang Rai be deleted and re apply afor Covid Ext in BKK? Thanks
