Hello, am Kenyan 21 yrs of age,, how can I join...

We would like to inform you that your question is not related to our field of work as legal consultants in the legal department. We are specialized in providing legal advice to our clients.

In addition, the site does not have any relation with any government or private entities

If you are a Kenyan National and not residing in the US then you cannot join the US army,

That’s because in order for a non-citizen to enlist in the military you must first be a legal immigrant (with a green card), and a permanent residident in the United States.
