Did I submit the correct filling fee?
- Yes
Is this an error of NSC?
- Yes
Should I contact NSC now to correct this? What is the standard procedure to due this kind of situation?
_ I would make a copy of I-140 with USCIS date stamp and rejection letter, then send the whole package back. Include a letter to explain the situation and print it on a colorful sheet.
Will I still get a priority date of July 27, 2007 for I140/485 concurrent filling?
- Should be
Should I file the case again when waiting the response from USCIS?
- Don't wait
Following link is for your reference, since it is from AILA not from USCIS, and no source link available.
