Applicants are required to set up an account and submit visa applications as an individual, or apply through travel agencies as previously, where travel agencies will submit online applications on their behalf. However, supporting documents have to be attached and payment of visa fee in pound sterling (£) has to be made online through secured portal. There will be no refund if visa application is rejected, or applicants paid for multiple entry visa but only eligible to get single entry visa.
Applicants can either book an appointment to submit their passports and visa applications in person at the Embassy, or submit them by post.
Please note that the Royal Thai Consulates in Cardiff, Gibraltar, Glasgow, Hull, and Liverpool in the UK, and in Dublin, Ireland, will continue to receive and process visa applications in the same way. Those who wish to apply for visa at the Royal Thai Consulates can continue to do so as usual.
