Traveling to Chile

Traveling to the United States

In order to work in the U.S., an employee must be on a VISA that permits work and he/she must have a Social Security Number. "Work" is defined as any activity that an employee is paid to do. Any work that an employer permits an employee to perform is considered compensable time under the wage and hour laws. When an employee travels to the U.S. to attend meetings, training, etc. during regular business hours, and your employer pays you, then this is considered work.

An employee must have prior approval to work in the U.S. In order to “work” in the U.S., HR must confirm the employee is on the correct VISA and has a Social Security Number. Payroll Manager Lisa Irvine (lirvine@nrao.edu) must be notified at least 30 days in advance before arriving in the United States. Employee will then go through Glacier and complete necessary paperwork for Human Resources. Once the online Glacier application is complete, employee must fill out appropriate State tax form and return to Human Resources.
