Yes, that is correct.
On or after March 9, 2021, applicants and petitioners should not provide information required solely by the Public Charge Final Rule. That means that applicants for adjustment of status should not provide the Form I-944, Declaration of Self-Sufficiency, or any evidence or documentation required on that form with their Form I-485. Applicants and petitioners for extension of nonimmigrant stay and change of nonimmigrant status should not provide information related to the receipt of public benefits on Form I-129 (Part 6), Form I-129CW (Part 6), Form I-539 (Part 5), and Form I-539A (Part 3).
If an applicant or petitioner has already provided such information, and USCIS adjudicates the application or petition on or after March 9, 2021, we will not consider any information provided that relates solely to the Public Charge Final Rule, including, for example, information provided on the Form I-944, evidence or documentation submitted with Form I-944, and information on the receipt of public benefits on Form I-129 (Part 6), Form I-129CW (Part 6), Form I-539 (Part 5), and Form I-539A (Part 3).
