He cited the fact that repeated deployments place much strain upon one soldier's family and himself which, in turn, can affect retention. A similar bill to Rangel's 2003 one was introduced in 2007, called the Universal National Service Act of 2007 (H.R. 393), but it has not received a hearing or been scheduled for consideration. At the end of June 2014 in Pennsylvania, 14,250 letters were erroneously posted to men born in the 19th century calling upon them to register with the Selective Service. This was attributed to a clerk at the Pennsylvania Department of Transportation who failed to select a century during a transfer of 400,000 records to the Selective Service; as a result, the system did not differentiate between men born in 1993 (who would need to register) and those born in 1893 (who would almost certainly be dead). This was compared to the "Year 2000 problem" ("Y2K bug"), in which computer programs that represented years using two digits instead of four digits were expected to have problems beginning in the year 2000. The Selective Service identified 27,218 records of men born in the 19th century made errantly applicable by the change of century and began sending out notices to them on June 30. On June 14, 2016, the Senate voted to require women to register for the draft, though language requiring this was dropped from later versions of the bill. In 2020, the bipartisan National Commission on Military, National, and Public Service issued a final report recommending that the military improve enlistment rates through improved outreach and recruiting rather than a renewed draft. However, it also recommended that the U.S. Department of Defense perform regular national mobilization drills to rehearse a recommencement of the draft. In 2020 and 2021, bills were introduced in Congress either to repeal the Military Selective Service Act or, alternatively, to replace all references to "male" in that act with non-gendered language. Either of these proposals, if enacted, would remove any gender and sex conditionality related to the draft. Non-citizens The Selective Service (and the draft) in the United States is not limited to citizens. Howard Stringer, for example, was drafted six weeks after arriving from his native Britain in 1965. Today, non-citizen males of appropriate age in the United States, who are permanent residents (holders of green cards), seasonal agricultural workers not holding an H-2A Visa, refugees, parolees, asylees, and illegal immigrants,
