Who can apply for Navy OCS?

The eligibility for applying to Navy Officer Candidate School (OCS) includes U.S. citizens as a primary requirement, but it also extends to select foreign nationals under specific circumstances. This can occur through a process that allows certain individuals, such as those with special skills or qualifications relevant to the Navy's needs, to apply for OCS. Thus, the inclusion of select foreign nationals acknowledges that there are instances where non-citizens may be considered for officer training, provided they meet all other requirements and obtain necessary approvals.

In contrast, the other options are more restrictive and do not accurately reflect the broader eligibility criteria set by the Navy. For instance, stating that only U.S. citizens can apply does not account for the possibility of select foreign nationals meeting specific criteria. Similarly, the suggestion that permanent residents are eligible without mentioning the advanced approval for foreign nationals misrepresents the Navy's policy. Lastly, limiting applications strictly to high school graduates excludes those with higher education qualifications who might already have completed college degrees and are seeking commission through OCS. Understanding these points highlights why the choice encompassing both U.S. citizens and select foreign nationals is the correct answer.
