School of Infantry (SOI) Graduation Dates

Your Marine has successfully graduated from boot camp and is off to the School of Infantry (SOI). If Marines went to boot camp at MCRD Parris Island then they will be attending SOI East. SOI East is located at Camp Geiger, North Carolina. Marines who attended boot camp at MCRD San Diego will go to SOI West located at Camp Pendleton, California.

For all the information you need for the Marine Corps School of Infantry, download our free guide or read more on what happens after Marine boot camp.


Marines will report either to Infantry Training Battalion (ITB) or Marine Combat Training (MCT) upon arrival at SOI. Depending on what your Marine’s Military Occupational Specialty (MOS) is will determine which school they will go to. For Marines with an infantry MOS (03xx) training will continue at ITB. All other Marines will train at MCT.

Although Marines will have more freedom during SOI, they will still be out in the field and away from their phones for long periods of time. You can still send Letters to your Marine while they are at SOI. Follow the steps below and use the guide to find your Marine’s new address.

  1. Use these graduation date charts below to find your Marine’s Company and Class for the School of Infantry (SOI).
  2. Once you’ve identified your Marine’s Company & Class information, visit our School of Infantry (SOI) – East & West Mailing Address Guide.

Author: Nicole at Sandboxx

The daughter of a United States Marine, I grew up with a passion and love for our troops, which led me to pursue a career in a field where I could give back to the military community. In my free time you can find me spending time with my significant other who is currently an Officer in the Marine Corps.

  1. My sons start date was 11/14 should graduate 12/12. He told me he was golf co but the list here says India. He’s at camp Geiger.

  2. I haven’t heard from my son since he left on November 14, 2017. I need to know if he’s doing ok. Can someone help me find out this information? Thanks Ann

  3. We are trying to update my son’s address in Sandboxx for his time at MCT. We can figure out class and company, but not platoon. Any help?

    1. Good afternoon, John. Thank you for the feedback. We’ve confirmed that you’re correct and the Class is 12-18. We’re updating our blog information. Thank you for using SANDBOXX.

  4. I’m not quite sure what my sons address is. He arrived SOI ITB Jan. 16, but is waiting and says he will be picked up Jan 23.

  5. My grandson is currently on leave. He has an additional 7 days of leave because he agreed to be a Recruiter’s assistant. He is going to be at 29 Palms for his SOI. I’m not sure when he leaves. He graduated from MRCD on January 12. Im just trying to figure out what his mailing address will be.

    1. Good evening, Ron. The Platoon number they use at boot camp is totally separate from their address at SOI. Please reach out to our customer support team at for any questions you might have. Thank you for using Sandboxx.

  6. Brian,
    I am Nate Hoppe’s grandmother, Judy Hoppe. His girlfriend and I would like to write him but we can’t.figure out where he is. We came up with PVT, India Class 25-18 with the Pendleton address. Her letter has been returned. Can you help us out.

    1. Good morning, Judy. Our Customer Happiness Team updated Nate’s profile address in the app. You will just need to search for his profile and when you see it, select his profile and his address will autofill on the next screen. Please reach out to for further assistance. Have a great day!

    1. Hi, Jenn. We haven’t received any updates on this matter at this time. Hurricane Florence has impacted the dates of School Of Infantry. We’re waiting patiently for an update. As soon as we know anything, we will update this information. We hope this helps. For more detailed assistance, please email We would be happy to help.

  7. My son just graduated 10/5. His orders say he leaves MCPI on 10/12 and report to SOI 10/23. Well he left MCPI 10/5. So shouldnt his orders say 10/05/2018 -10/16/2018 instead? He said all his platoon orders say that. So do they get extra leave and how do I find out all this information?

    1. Hi, Kimberly. We recommend reaching out to his recruiter for more detailed information. We hope this helps.

  8. I thought that I had read on your app that you provided paper and a stamped addressed envelope with each letter sent. My marine said she only got the envelope. No paper and no stamp. I wouldn’t of payed for your app if I had known this. RIP off.

    1. Hi, Tina. We only include the pre-addressed return envelope. We changed our policy on 2/17/2018. Only users who signed up in the app prior to that date get pre-paid postage. Any users who signed up after that date do not have that included. We haven’t included paper in our letters for quite some time. We’re sorry if you weren’t aware of that.

  9. Do you provide additional information on MCT Graduation. I found tons on BootCamp but having difficulty locating details for MCT Graduation. I appreciate all of your help!

  10. Thanks for being so helpful. My son will be graduating basic from Parris Island 12/14 and I’m wondering if there’s an SOI at Camp Lejeune? I’ve heard yes and no-and as of now have not had a chance to talk to him about it. Do you have any information on this or is Camp Geiger the only place? Thank you again!

    1. Hey Donna,

      If your son is graduating from Parris Island then he will go to Camp Geiger for SOI. Camp Geiger is a satellite facility of Camp Lejeune, both of which are located in Jacksonville, North Carolina. We wish him the best of luck!
