if it's at NVC, send a cover letter and a copy of a nat. certificate there, takes a couple of months.Thanks a lot. I have my I-130 approved long time back, I think calling them for upgrade would be a better option. Do you have a rough idea of how long it takes for this upgrade to be completed? from the day I sent out the nat cert, receipt number copy.
Filing a new I-130 is useless, since the priority date will be new and the waiting will start all over again. Do not tell people to do so.Else just file a new I-130 as a USC and pay again.
