to reducing illegal immigration would be to reduce the job opportunities available for undocumented immigrants. He has said that requiring employers to confirm each worker's immigration status using an E-Verify-type database, such as in Arizona, and punishing employers who hire workers lacking proper documentation, would lead employers to stop hiring undocumented immigrants, with the result that fewer immigrants would choose to come to the U.S. illegally, and many of those who are already in the U.S. would "self-deport." In June 2012, President Obama issued an executive order instructing officers of the federal government to defer deporting young undocumented immigrants who had been brought to the U.S. as children and who met certain requirements, such as serving in the military or being successful students. The executive order was intended to temporarily implement parts of the DREAM Act until a permanent fix could being agreed upon by Congress and the White House. When Romney was asked his opinion of the president's executive order, he responded by saying that he would reveal his own long-term policy on the subject at a later date. Romney later said that he would respect the work permits that Obama had granted. In terms of promoting more legal immigration, Romney has proposed loosening immigration rules to increase the entry of highly skilled immigrants into the U.S., allowing more high-skill visas to be granted and raising the quotas of high-skilled immigrants allowed from certain countries. Romney has noted that high-skilled immigrants are more likely to start companies and create jobs than other immigrants. He has said the U.S. should grant permanent residency to "every foreign student who obtains an advanced degree in math, science, or engineering at a U.S. university." He has also proposed streamlining the temporary worker visa issuance system so that temporary agricultural and tourism workers could be processed more efficiently. He would seek to speed the processing of immigration applications for close family members of legal residents so that families do not have to wait years to be reunited. During his Utah Senate campaign, Romney said that he believes in welcoming immigrants and rebuked Trump's anti-immigrant rhetoric. Romney's support for immigration in his ad "reflects the moderate position of many Utah Republicans on immigration, which is shaped by the progressive stance of the Mormon Church here as well as the individual experiences of many Mormons during their two-year missions abroad."
