Today I received this email
Dear Mr Lainton
As part of the application process for your child’s passport we need to see you and I have attached a letter inviting you to attend an interview on Monday 9th January at 15:00pm at the UK Visa Application Centre in Baghdad.
Please Respond to this email within 7 days, to confirm your attendance, otherwise we will offer the appointment to another customer.
