Ok so i've know noticed the word 'PRIOR' in "to complete additional forms that are required PRIOR to providing the requested information to the Airmen Certification Branch,"

What would be the procedure now then? I've filled out the forms to the CAA and i'll get them posted tomorrow morning. How do I know the both authorities will communicate with eachother? I've not gone through this before so it's all new to me and probably the first big hurdle...
