TSA Pre-check and CBP Global-Entry


Registered Users (C)
I received GC couple years ago, and recently I took up a travelling job, and missed flights couple times due to long lines at security check.

Permanent residents are eligible for both, TSA Pre-check and CBP Global-Entry programs. Did any of you apply for them? What kind of queries we need to go through? Are we asking for a review our immigration records by applying?

TSA Pre-check fee is $85, and CBP Global-Entry fee is $100. I prefer to apply for Global Entry as the fee difference is very little.

Thanks in advance.

PS: "Start early" is a good option, but we can't walk away when a client is talking to us.
