Immigrants who work in Arizona or other parts of the U.S. on H-1B visas may have to deal with evolving political and legislative landscapes thanks to President Donald Trump. Although Trump has long spoken out against potential flaws in the immigration system, in mid-April 2017, he took what some observers say was his first official move in efforts to bring change to federal work visa programs. Although some legal observers said that his actions lacked teeth, they could represent a shifting tide of official federal policy and open the door to more formal legislation that favors American workers.

Trump’s executive order directed a number of federal entities to devise new reforms for the H-1B visa program. According to the text of the order, these changes should promote policies that guarantee that visa winners have high skills and fulfill high-paid job positions.

April marked the first instance in many years of H-1B applications falling below 200,000 following years of high demand, according to the U.S. Citizenship and Immigration Services. The presidential order didn’t provide many specifics for how to implement reforms. Some immigration proponents, however, remained hopeful that letting individual agencies make such determinations might actually benefit H-1B seekers by improving the quality of job markets and reducing the incidence of low-paying outsourcing firms using up available visa slots.

Immigration reform is a major concern for countless people trying to gain their citizenship or support their families with work visas. Changes in the way laws are written and enforced might mean that formerly legal immigrants suddenly find themselves on the wrong side of the law, which can jeopardize everything they’ve struggled to achieve. Those who want to navigate the evolving system effectively may benefit from learning more about the law by speaking with an attorney.
