With no advance warning, U.S. Citizenship and Immigration Services (USCIS) revised more than 40 forms on the Friday of the 2016 December long holiday weekend. The forms all have an effective date the same day the notice was posted on its website, December 23, 2016. For most of the forms, no previous editions are acceptable, except for the Form I-129, Petition for Nonimmigrant Worker. However, USCIS has indicated that it may apply discretion when receipting forms sent around that date, rather than rejecting them outright. Affected forms include the following:

I-90, I-102, I-129, I-129CW, I-129F, I-130, I-131, I-131A, I-140, I-191, I-192, I-212, I-290B, I-360, I-485, I-485 Supplement A, I-525, I-539, I-600, I-600A, I-601, I-601A, I-612, I-690, I-694, I-698, I-751, I-765, I-800, I-800A, I-817, I-824, I-910, I-924, I-924A, I-929, I-942, I-942P, N-300, N-336, N-400, N-470, N-600, and N-600K.

This change will affect green card renewals, business immigration cases, family immigration cases, work authorization applications, citizenship applications, and other types of cases. USCIS did not disclose the reason for the unanticipated change. Persons with concerns about impact on immigration status should contact an immigration attorney.

Filing fee increases for a number of the forms were effective December 23, 2016, as well, but USCIS had given prior notice of the fee increase.
