FYI for anyone wanting to get a non B at Liverpool UK you need to call them, they will send you an email requesting you scan and send the documents to them by email. They then send it to London to be pre approved and then offer you an appointment to collect. £70 for same day collection.
Side note- the guarantor, I put my mother for UK and left Thailand blank.
I sent it yesterday, it was approved and I received my appointment within 4 hours!
