This week United States Citizenship and Immigration Service (USCIS) issued a Policy Memorandum titled “Rescission of Guidance Regarding Deference to Prior Determinations of Eligibility in the Adjudication of Petitions for Extension of Nonimmigrant Status” which rescinds prior USCIS policy guidance permitting USCIS adjudicators to give deference to certain previously approved nonimmigrant visa petitions where the material facts underlying the petition remained unchanged. This policy had been in place since 2004 and was reaffirmed by USCIS in 2015.
