The Employer Web services Interface Control Agreement (ICA) contains the information you need to develop and test your software interface. You must enroll in E-Verify to develop and test Web services applications. Once you enroll and sign your memorandum of understanding, you can request the ICA by sending an email to VISWebServices.Test@uscis.dhs.gov.
Adopting Web services access method requires a significant amount of time and financial investment to develop, test and implement a software interface. You will still, however, be required to comply with the E-Verify federal contractor time requirements. Employer access to E-Verify is the default access method and, using this method, you can create and process cases in E-Verify immediately after enrolling as an employer.
The Web Services resource page is available to E-Verify participants only after they request to add Web Services as an access method.
