Am I able to drop out of Army ROTC and still fulfill my contract by enlisting into the Marine Corp?

Let me get this straight, you have spent 4 years preparing to be an Officer in the Army, and now you decide to go to the USMC? But check with a recruiter.

Navy Federal Credit Union or USAA could probably give you a loan for the last semester. My advice, is to do whatever you can to finish the degree.

I left Navy ROTC after 3.5 years, finished my degree on my own. Then enlisted in the Army and after 2 years my debt was relinquished. It was a painful process getting it dropped but $36,000 going away was nice. Now I’m a WO in flight school. Do what makes you happy man and it will work out.

The Army is not a 2nd class service. I don't know what your mos would be, but in infantry every action is well coordinated augmented with excellent training.

I understand everyone is telling you to get a loan, but as I understand with ROTC, since you dropped out you have no chance of meeting the time obligations. I actually saw something similar happen to a guy who finished his degree a year early and had to enlist because he broke the terms of his contract.
Enlisting in the Marines won't satisfy the terms of your contract any more than it would to borrow money from your uncle John and pay it back to your uncle Bill.
The Army is filled with people who left the Marines. The Army has more opportunities, larger branches, and better promotions. You should search through some of the threads on here to see what people have said about their experiences being in the Army after the Marines. If you want to go Infantry, Infantry is pretty much the same everywhere. You'll find that an infantry platoon looks the same in the 82nd, the Marines, and the 101st.

Sorry to hear about issues stopping your admission process. Ultimately you will need to talk to the counselors at your school as they will be the ones to fill out the application anyway. My school had two officers who went enlisted rather than commission but they we both Army not a sister service.

Something is missing from your question and statements. Where’s the bottom line? You speak of personal and financial issues, yet want to enlist in the Corps with a possible scholarship repayment debt hanging over your head?

There is not enough information here to offer any truly relevant advice and recommendations other than you need to have a sit down with your PMS and have an open conversation about your future and the military as a career. The PMS should be able to offer you the best point of fact advice.

Have you Read your own contract?

Lots of people are throwing out advice, but none of them are answering your question.

The cadre (probably one of the administrative staff) of your ROTC unit can give you the actual answer.

But unless things have changed since I was in ROTC (25+ years ago), the answer to your question is *probably* yes. Technically, the Army can probably require you to serve in the Army or pay back the scholarship, but the purpose of the service obligation is to discourage people from gaming the system by having Uncle Sam pay for most of their school and then dropping out of the program, so the US government's interest is for you to serve in *some* branch of the military.

You can't get a college loan to pay for the last year? - This makes absolutely no sense.
Try Great Lakes, Citizens One, Wells Fargo, CommonBond or even Discover Card Loans.
Either way you are in debt - either to a loan institution or the debt of a service obligation.
