International Policies & Procedures

All new international employees required to go into the Foreign National Information System (FNIS) to enter their immigration history information.

Webster University uses FNIS to collect data on all foreign nationals employed at the institution. FNIS will automatically calculate your Tax Residency Status and analyze if you are eligible for Tax Treaty benefits. Tax Residency Status determines how employers can properly withhold taxes, how the individual should complete the W4 withholding allowance form, what income is taxable, which tax forms must be completed for a tax return, and even whether a tax return is required.

Please contact the Payroll Department for your FNIS login information at payroll@webster.edu or call 314-246-7408.

  • Copy of I-9 (Employment Eligibility Verification Form)
