Foreign citizens serving in the US military is a highly charged issue, which could expose the Pentagon to criticism that it is essentially using mercenaries to defend the country. Other analysts voice concern that a large contingent of noncitizens under arms could jeopardize national security or reflect badly on Americans' willingness to serve in uniform.
The idea of signing up foreigners who are seeking US citizenship is gaining traction as a way to address a critical need for the Pentagon, while fully absorbing some of the roughly one million immigrants that enter the United States legally each year.
