The latest version of Form I-765, coupled with an information sharing agreement between USCIS and the Social Security Administration (SSA), just streamlined the process of getting a Social Security number assignment. The single form – the updated Form I-765, Application for Employment Authorization includes questions on whether the applicant already has a SSN card and, if not, whether they want one produced. This will eliminate the step of going separately to the SSA once the Employment Authorization is produced. Until now, applicants had to submit a Form I-765 to USCIS for an EAD, and then submit additional paperwork in-person at their local Social Security office to obtain an SSN.
The 07/17/17 version includes additional questions that allow applicants to apply for an SSN or replacement card without visiting a Social Security office. Use of the form is currently optional but is mandated effective 12/04/17.
Applicants who receive their approved EADs from USCIS should expect to receive their Social Security card from SSA within the following two weeks.
