United States Citizenship and Immigration Service (“USCIS”) has updated its guidance on how to calculate the age of a child applying for adjustment of status under the Child Status Protection Act (“CSPA”).  Under the new policy,  USCIS will use the State Department’s monthly Visa Bulletin “Dates for Filing” chart, as opposed to the “Final Action Date” chart in order to protect child adjustment of status applicants who risk aging out of availability to obtain a green card as derivative beneficiaries of their parents’ immigrant petitions, upon reaching age twenty-one.
