According to a draft of an executive order issued by President Donald Trump, technology workers who have H-1B visas would need to provide updated certifications. These certifications would confirm that they weren’t taking jobs from American citizens living in California or other states. If the executive order were to go into effect, it would likely result in a ban on new work visas for up to 90 days.

Workers who are part of the food supply chain would not be impacted by the president’s actions. The same is true of those who work as medical researchers or who otherwise work in the health care sector. There was no word as to what could happen to those who can’t certify that they aren’t taking a job from an American worker. It was also unclear if the ban would apply to those who may be seeking an extension of a valid work visa.

As a general rule, it is possible to immigrate to the United States for the specific purpose of obtaining employment. Those who have specialized skills or knowledge may be able to apply for H-1B or other types of work visas. In some cases, it may be possible for a spouse or children to accompany a visa holder to the United States. Family members may also be allowed to obtain authorization to work while living in America.

Those who have questions about the employment immigration process may want to speak with an attorney. Legal counsel may also be able to help a client fill out paperwork or take other steps towards permission to work in the United States.
