On 21 May, US Citizenship and Immigration Services (USCIS) issued Policy Memorandum PM-602-0199. It amends no statute. It eliminates no green card category. It will never appear in the Federal Register. And yet, for the more than one million foreign nationals waiting for permanent residence from inside the US, it may prove to be one of the more consequential immigration policy shifts in recent years.
The memo reframes Adjustment of Status, the process by which a foreign national obtains a green card without leaving the country, as "a matter of discretion and administrative grace" and "an extraordinary relief."
In practical terms, the USCIS is instructing its officers that approving a green card application from within the US is no longer a routine administrative step at the end of a long eligibility process.
