19 y/o looking to join marines after school, medical concerns (specifically related to allergies)

I'm currently a junior at a college studying CS + Econ with a minor in math.

Long story short I want to commission and join the Military post grad for a few years. It's kind of a personal reason (I'm a legal immigrant + naturalized citizen and I'm thankful to the US for everything it's given me. (I know look at the naive kid ha ha ha)). Anyways I have a few friends at school who are vets and I've gotten the summary of what it is, good and bad. I'm still interested in joining for Infantry / Combat Arms. Preferably the Marines, but also will look at the Army / Navy.

Physically I'm pretty skinny but I ran Varsity long-distance XC / TF in HS, I practice brazilian jiu jitsu, and I lift weights consistently (6 times a week). I'm going to begin specifically training to crush the fitness tests and gain more mass so that I have the best chances of getting through OCS applications once I graduate.

I have two major concerns.

- I have a GPA of 3.2, massive upward curve here, I had a really tough first quarter and I'm hoping my school's status (T10) will help. I'm on track to achieve a 3.4/3.5 by the time I graduate. Is this up to academic standards?

- Medical (real concern): I have a minor tree nut allergy, A VERY MINOR ONE (unfortunately it's in my records for when I went to see an allergist as a 16 year old (I was applying to USMA before I received the offer at my current uni)). For reference, I am technically allergic to only some tree nuts, mainly only hazelnuts and walnuts. However I eat nutella sandwiches every other day (I love nutella) and the most major symptom I have is mild sneezing / light throat itch. My records show a shellfish allergy when I was 9 but by the time I turned 16 I kind of just grew out of it and it disappeared when I had another skin bump test. I eat shrimp / lobster just fine nowadays and it seems it's getting that way for the tree nuts as well (regularly eat protein bars w/ tree nuts and such). Walnuts I don't really eat a lot of but it's the same situation (throat itch).

How screwed am I? Am I absolutely toast for MEPS / will I have to go through the waiver process? I do experience symptoms (however minor) and I was wondering what I can do right now to try to make the process easier for myself upon graduation. (I would want to commission as soon as possible).

Thank you all for your help!
