Is there a way for me to check a biometrics appointment availability before paying for a UK visa application in the USA? I have applied for a Schengen visa and depending on the approval/rejection of the visa, I plan to apply for a UK visa. However, I do not want to wait until after I get the Schengen visa to book an appointment if the appointment availability is far off. If availability is easy, I will wait it out.

Is there a way to determine appointment availability without paying for the application? I did not find this option in the gov.uk website.
