An employee who is not a United States citizen is covered by IMRF like a citizen if he or she meets the 600- or 1,000-hour standard (see 3.65 A. Annual Hourly Standard [600- or 1,000-Hour]).
Persons hired after November 6, 1986, should furnish the employer with verification of eligibility to work in the United States (Alien Registration Receipt Card I-551, called a ”green card,” or Employment Authorization Card I-688A).
