I am here on a single entry visa valid until end of October, and I would like to extend for one more month, as I will leave end of November. The thing is I had few pages left in my passport so I got a new passport in BKK.
To do the extension in my new passport will I have to pay more than the normal extension?
Or another option is to do a Ranong border run, for an additional 30 days. Will I have problems doing this with two passports?
