Thx andhraguy ! USCIS just confirmed that they will honor the DOF chart !!
For Employment-Based Preference Filings:
USCIS will not accept any new employment-based fifth preference adjustment of status applications based on the Regional Center Program until that program is reauthorized. For all other employment-based preference categories, you must use the Dates for Filing chart in the Department of State Visa Bulletin for October 2021.
Are you saying that if I had the package ready now, I could have shipped them NOW with a delivery date of 1st October ?
