The attorney Fan posted the key responses from Adjudication Manager of the USCIS Vermont Service Center to the questions asked by members of the DC Chapter of 美国律师协会. Among them, one question was: Can dependents file I-485 (Applications to adjust status), if the principal applicant has already filed, despite the fact that the visa numbers have retrogressed? And the answer was: No, in order to apply for an I-485, a visa number must be immediately available. At this time, in certain categories and for certain foreign nationals, a person cannot apply until the priority date is current.
My question is: What's the Priority Date for dependents since we don't file I-140 separately for dependents?
Thank you in advance for your answer!
