"A leading Republican in the Senate on Tuesday unveiled legislation to raise the number of temporary visas for skilled technical workers from foreign countries, but prospects of passage this year could be clouded by election-year politics. Senator John Cornyn, the senior Republican on a panel that oversees immigration, introduced a bill that would make an additional 55,000 visas available each year for graduates with master's and doctoral degrees who have studied at U.S. research institutions," the Chicago Tribune writes.

"A Newark Liberty Airport security supervisor pleaded not guilty to identity theft Tuesday as new details emerged about his alleged 20-year odyssey of deception, including that he may have assumed the identity of a New York man weeks before the man was murdered. Through his court-appointed attorney, Nigerian Bimbo Olumuyiwa Oyewole pleaded not guilty to one count of identity theft, a second-degree offense punishable by a maximum 10-year sentence," CBSNews says.

"As the Alabama Legislature's regular session draws to a close, the Senate is expected to take up a measure to tweak the state's toughest-in-the-nation immigration law. The House passed the changes on April 19. They include clarifying that the law won't prevent religious groups from providing charity to illegal immigrants. They also stop schools from asking for the immigration status of students before they enroll," WSFA reports.

"Four protesters were arrested on Tuesday when about 100 people opposed to immigration policy, war and economic injustice marched on a Chicago courthouse and then through downtown, police said. In a week of expected protests leading to the start of a NATO summit, a Chicago priest from Our Lady of Guadalupe Anglican Mission and a woman were arrested after refusing to leave a federal courthouse that hears immigration cases," the Chicago Tribune reports.

"This week the House is debating the reauthorization of the 1994 Violence Against Women Act, and there seems to be little danger of a relapse of the relative bipartisanship that occurred at the end of April, when the Senate approved its version of the bill," says Opensecrets.org. "Even before things got tense, 44 organizations were registered to lobby on the bill as of March 31 -- including, somewhat unexpectedly, eight Native American tribes or groups working on their behalf and several immigration groups."

"The case of an undocumented Mexican in South Carolina who is fighting deportation with support from U.S. Rep. Luis Gutierrez (D-Ill.) will put the validity of the authorities' new discretionary policy to the test. The fate of Gabino Sánchez, 27, will be decided Tuesday at an immigration court in Charlotte, and for Gutierrez it will shine a light on whether the Immigration and Customs Enforcement memorandum giving priority to expelling undocumented criminals 'carries any weight,'" says Fox News Latino.

"Sen. John McCain (R-Ariz.) made an appeal to Hispanic voters Monday, saying that that Mitt Romney would address 'the need for immigration reform' and that the presumptive GOP presidential nominee did not think self-deportation was 'the entire answer to the issue,'" says The Hill.

Meanwhile, "In an interview with Newsweek's Andrew Romano, Martinez takes aim at 'self-deportation,' an idea promoted by Romney during the GOP primary and one at the heart of Arizona's controversial S.B. 1070 anti-illegal immigration law," says the Washington Post.
