Your document list looks pretty good, though you don't need the floor plan of the property.
- I believe you do need to purchase 2 return shipping labels.
- For the priority processing, just make sure you purchase the correct one... Settlement Priority Service for $771 (not regular Priority for about $189).
- There is a glitch with the IHS surcharge payment website where it says that children don't have to pay the £600 fee... this is incorrect, however, it may not let you pay it for the child. If this happens, you just need to send the application without the IHS payment for the child, and then Sheffield will contact you to ask for the payment when they are processing the application.
- For the biometrics, you print the appointment confirmation letters, and they are then stamped at the biometrics appointment.
Can I just check that you have Appendix 2 of the Armed Forces paper form?
There are two Armed Forces paper forms - one is the equivalent of the online form and the other is the financial requirement appendix. I'm not sure if you need to complete the main Armed Forces Appendix (VAF(AF)) as well as the online form, or if you only need to complete Appendix 2.
So, you definitely need:
- the online application form (selecting the correct HM Forces options)
AND
- Armed Forces Appendix 2 (

And you may also need:
