Okay, the first email is the instruction for people applying in the US. The second email is a generic instruction for all applications, but not everything will apply... in some countries you submit the documents in person at the biometrics appointment, so you need to take everything with you.
But in the US, you don't do this, so you don't need to take the application or the documents with you.
The biometrics process will be as follows:
- You take with you your passport and the printed biometrics confirmation letter.
- They will check your passport and confirmation letter, make sure your details match and stamp the confirmation letter
- They will take your fingerprints and photo and send you home. The whole appointment should take no longer than 5-10 minutes
- You place your stamped biometrics confirmation sheet and passport in the package with the rest of your documents and mail them to Sheffield.
