So we booked a flight to Thailand for next February 27, back to the UK on April 1 and it just dawned on me this is more than 30 days. We went in 2023 and got 1.5 months tourist visa upon arrival, however this year we only got 30 days tourist visa upon arrival. Do we need to get a visa from the embassy in the UK before we go or can we ask immigration upon arrival to grant us 32 days, please?
