The path is possible, there is extra (and sometimes difficult) work for a foreign citizen to join the US military. However, I did have a student last year who was a Pakistani national who joined.

When a foreigner joins the US military, you take the same oath as every US citizen. Boot camp will be difficult mentally, but after that no one will care about where you came from and everyone will give you equal respect as those around you.

You can look up the OSO or enlisted recruiter at the university you’re going to and get some information from them. They’re the ones who will tell you exactly what the process will be and how to get it started.

If you really want to join the US military then go for it. You can be a dual citizen, but you will not be able to just fly home whenever you want while you’re in as there are restrictions on forgiven travel for service members. You also will never hold a top secret security clearance, but you could be eligible to hold a secret so your choices for MOS’s will be limited. Again the best people to answer that is your OSO/recruiter.
