Employers who participate in E-Verify+ can use both processes. Employers may determine which is best on a case-by-case basis, but may not direct or use one process over another for a discriminatory purpose, such as by directing certain employees to use E-Verify+ based on citizenship, immigration status or national origin. Employers select whether to create an E-Verify+ case to complete their Form I-9 and employment verification together, or to create a traditional E-Verify case after Form I-9 sections 1 and 2 are completed.
