Both are correct. 'United States Army' is formal and official; 'U.S. Army' is a very common abbreviated form.

Yes, when it is part of the proper noun or clearly referring to this specific institution (e.g., 'He joined the Army'), it is capitalized.

Can a non-US citizen join the United States Army?

Under specific conditions, yes. Non-citizens with legal permanent residency (green cards) may enlist. Citizenship is often a requirement for certain roles and clearances.
