Hi I applied for covid visa extension in chiang mai and received under consideration stamp told me to come back in 15 days,

I’m now in Phuket, is it possible to get Phuket immigration to sign this off? if not, am I able to post my passport for someone to get stamp for me rather than spending a whole day flying up and down?

They didn’t tell me about the 15 day thing until after I applied and got my stamp or I would have applied in Phuket

Living near Reading, UK what's the best choice for 72 hour Covid test. Do they also provide the FTF cert?

Do they email the results?

Thanks for help
