got caught with a fake id what should I do?

Hello guys I am a college student and recently I was buying some alcohol with a fake id and got caught in some excise tax police undercover operation. They asked me how I bought it and I did not lie to them I straight up told them I had a fake id since I remembered seeing one of the undercover cops walk out of the store when I was at the counter.

I ended being charged with: (1) Illegal possession of an alcoholic beverage. (2) possession by minor of false or fraudulent identification (3)def knowingly making false statement of age (4) furnishing alcohol to minor ( since when we left the store we put the alcohol in my friends bookbag.

They gave me a ticket with these charges and a court date. However on the ticket they have section were you can basically just admit and not have to go to court and pay a fine I think. This was my first time ever getting in trouble with the law the cop said if I go to court they will lump the 4 charges together and I will probably have to do some community service and a class or something.

However, I was planning on studying abroad next year and if I have these charges on my record it will probably fuck me up over when I apply for my visa so I need this to be off my record. Should I just admit or should I go to court. If I go to court is it okay if I get a public defender or should I try to find a defense attorney to pay ( I am low on money). Again this is my first offense ever and cannot afford to have this on my record! It will seriously fuck me over I am a good student with a 3.6 GPA and a bright future and I don't get in trouble. I have tons of scholarships and internships lined up. It was stupid but I need to figure out how to sort this out HELP!

edit- I am in Indiana*
