Hi Ksand24 I am not doing priority but I did see I could purchase it. I did not upload my document checklist before my appointment because it said I had to sign it at my appointment. I am going to mail it.
Yeah, it does not need to be signed at the appointment - that is incorrect information that does not apply to US applicants giving biometrics at an ASC. The checklist should be signed and uploaded at the same time as all your other documents. However, as you have not uploaded it already, I would mail it instead.
Your biometrics will be taken by US immigration on behalf of UKVI - they have nothing to do with your application, they don't care what visa you are applying for and you don't even need to take the checklist with you.
All you need to take to the appointment is your passport and the biometrics confirmation sheet. The appointment should only take around 5-10 minutes total
The normal procedure for biometrics is:
- arrive at the appointment where they will check your passport and stamp the confirmation sheet
- they will take your photo and fingerprints and then send you home
- Once you get home, you mail your passport and stamped biometrics sheet, along with your return shipping label and packaging to New York within 5 days
