? 1. What kind of visa are you applying for? Student Visa, Work Visa, Visit (Tourist) Visa etc.
? 2. Did you submit your passport as part of the application process.
If this was legitmate application with an agency acting on your behalf, you would need to submit your passport and the only way you would know that you had been issued a visa to enter the UK, is when your passport was returned to you with the entry clearance visa sticker fixed in your passport.
I still think that this is a scam and that eventually you will be asked for money.
