Can you provide some indication you read the threads that were linked to above instead of asking us to summarize them for you? Everything you need to know about the process is contained therein.
If you currently have 0 ops, reading those threads should more than clear up the fact that “one approach” (session? one approach?) is not sufficient.
Also, you start in IFATC as tower and ground only, so building up ops via Approach will help meet that criterion, and that one alone.
There’s still the training and written and practical tests for tower and ground, all of which requires a recruiter/trainer. One approach…session, I guess…will not make you an IFATC, no.
