Since November 13, 2009, the USCIS has been temporarily holding certain applications for adjustment of status (Form I-485) to allow the Department of Health and Human Services (HHS), Centers for Disease Control and Prevention’s (CDC) new vaccination requirements to become effective. The CDC recently announced a new criteria to determine which vaccinations will be required for the lawful permanent residency process. Under the new criteria, effective December 14, 2009, the vaccines for herpes zoster (zoster) and human papillomavirus (HPV) will no longer be required for immigration purposes. Consequently, the USCIS decided to hold any applications that would have been denied solely based on the applicant’s failure to receive the HPV or zoster vaccine as of Nov. 13, 2009 The USCIS will continue processing these applications on the effective date of the new vaccination criteria.
