Finally got my clearance. My recruiter has told me I’ll be enlisted as E-2. Where do I look for any proof?

It is in your contract. While you're at the MEPS signing a contract ask them to point out where it says you will be promoted.
Honestly, E2 is such a quick rank that it is not worth fighting over at the MEPS. You waited 7 months for a job that requires your clearance, it would be a shame to throw it away for a rank that they give away for doing well in basic training.

False promises in the Army happen. Usually, they’re small time issues. You should get your MOS and such, but you barely had a functioning sentence, so you should fix that if you want to be promoted above Specialist.

Ramos, anything anyone promises you must be in writing on your contract. If it's not on your contract, DD Form 4 or your Annex is is not true. Always read before you sign anything and if you have questions, ask. Your Recruiter should answer any questions you have. If they rush you, tell them to wait and answer your questions. If you don't feel comfortable, call me.
