What is the process and validity of the METV for UK citizens?

Did you appy for the single entry visa? When you enter you will get 60 days on arrival, can extend for an extra 30 whilst in the country.

Or if you were to leave the country and return on 23rd October, you will get a fresh 60 days that can be extended another 30 whilst still there. Apply for the extension after 6 weeks of the stamp, the extra 30 days will be tagged onto the new stamp.

E.g. arrive Oct 1st 60day stamp. Do land, sea, or air crossing around 22nd.

Arrive back by 23rd for a fresh 60 day stamp. Around Dec 4th apply for extension at local immigration office, get there for opening. Should be completed in a day.

Then you get extra 30days meaning you can stay in the country until Jan 15th

Jayne Stuart they ask for flight in and out. Outbound flight should originally be within 60 days, so you can refresh your allowance.

The last date showing on the visa is the last entry date you can have.

If you arrive back the day before your 60 days and possible 30 day extension is refreshed.

I hope thats what you're asking. If not let me know 😊

John Doughty 9th September. Means will loose a month of the visa but I thought it would take at least 15 -20 working days to process 🤯
