Today, December 23, 2016, USCIS posted a large number of new form versions. The forms all have an effective date of today, December 23, 2016, and the website indicates that no other versions of the forms are acceptable, with the exception of Form I-129. It appears USCIS is accepting prior version of Form I-129. No prior notice of these changes was given, and there was no alert sent to stakeholders today. Source: AILA Doc.
