Can my I-829 be denied if I use government welfare programs?

Public charge should not impact permanent residents if you are eligible for the benefits that you seek.

My understanding of the new public charge rules is that it is for the initial green card application. I had not seen that they are taking the new form I-944 with the I-829.

If you did not sign an affidavit, you should be fine.

It should not affect your I-829 considering the extraordinary circumstances in the country. However, it is advisable such assistance be temporary at best and it should not a permanent occurrence.

It should not since you are a permanent resident, provided you meet the requirements of any program you apply to.

Since the adjudication of an I-829 petition to remove the condition does not involve an adjudication by USCIS of your admissibility under the new public charge rule, taking government benefits should not affect your I-829, assuming you properly apply and qualify for those benefits.

I am not aware that you are required to prove you are not likely to become a public charge, to be granted the removal of condition as an EB-5.
