Since you pointed me in the direction of the Cisco reference I did go back and look. It was Brett Adam who reports this issue of the green card based on a conversation he had with Nancy. Lines 5 (second 5), 6, and 7. Brett does not indicate that Nancy sought assistance from low income or other services for immigration purposes. He goes indicate that Nancy told him an immigration lawyer was too expensive. He also indicates that Nancy told him that the proceedings were placed on hold until she got her green card through Cisco.
Reading that it seems reasonable to think that Nancy did not have a problem trying to obtain a green card and was comfortable believing Brad was managing the issue through Cisco. So I continue to believe she did not contact Interact for such assistance and that at least in her mind she did not think she had a problem with respect to obtaining a green card. Will clarify that she could have had a problem but was not aware - in other words maybe Brad was getting it done and maybe he wasn't. After the recent warrant on Cisco, I also think it is reasonable to think that LE knows the answer to this particular aspect.
Thanks for jogging my brain as to where this information was
