"Current law allows certain noncitizens who serve in the U.S. military to acquire expedited U.S. citizenship. Recent media reports have described situations in which noncitizen U.S. veterans who served in and were honorably discharged from the U.S. military, failed to petition for their citizenship for a variety of reasons, subsequently committed crimes that made them removable, and were then deported to their countries of origin. Although advocacy groups claim that there may be thousands of deported U.S. veterans outside of the United States, no reliable estimates have been produced for this population. In the 115th Congress, several legislative proposals have been introduced to address this issue."
