Tell the truth! Simple.

The Thai Embassy in London may require an interview, particularly for certain nationalities. They’ll typically check your identity, UK residence status, finances, travel history and plans, including accommodation and return travel. The main concern is whether you’re a genuine tourist who intends to leave Thailand within the permitted stay. An interview doesn’t necessarily mean there’s a problem with your application.
