USCIS will not allow the petitioner to use the priority date of a previously approved Form I-526 petition for a subsequently filed petition if:
The investor was already admitted to the United States under section 203(b)(5) of the Immigration and Nationality Act using the priority date of the earlier-approved petition; or
USCIS revoked the previously approved petition for fraud or willful misrepresentation by the petitioner, or because the approval was based on a material error.
