It looks like what happened in that post is a common administrative error where USCIS, instead of keeping the approved I-130 with the pending I-485 for Adjustment of Status, mistakenly forwarded it to the National Visa Center (NVC) for consular processing. Since you are adjusting status inside the U.S. and has already attended an in-person interview, you don’t need to go through NVC at all—the I-130 approval should have stayed with USCIS so that the I-485 could be adjudicated. When the I-130 gets sent to NVC, it creates a disconnect: the I-485 sits without final action because the underlying petition appears to USCIS as “completed and sent away.” The fix is to contact USCIS right away—through an online inquiry, phone call to Tier 2, or by submitting a written request—explaining that they are adjusting status in the U.S. and requesting that the I-130 be “recalled” from NVC and linked back to their I-485 file. Sometimes, congressional assistance can speed this up because USCIS will respond faster to inquiries from a senator or representative. If NVC has already received the petition, the person should also contact NVC (via their public inquiry form) to confirm they will send it back to USCIS upon request. Once the petition is returned, USCIS can move forward with final adjudication of the I-485. This mistake is frustrating, but it’s fixable—many people have had their cases corrected this way and received their green cards once USCIS linked the files again.
