How to know if I-140 is approved when submitted concurrently with I-485?

With the case number you may check the status on line. If not you will need to check with your employer or the employer's attorney

If the I-140 is an employer petition you need to discuss with your employer about taking it over. The I-485 is your application and you may take it...

I130 is delaying alot

60 days is not out of the ordinary. Probably will receive something from the NVC if that is where the mater is pending in another 30 to 60 days.

I got approval petition with wrong DOB.

You need to have the attorney or the employer that prepared the petition contact CIS to have the error corrected.
