my husband and I are separated about a month and I want to know how he can cancel my I-485 application without my knowledge. He is very smart from beginning he didnot even file for my EAD bluffing me saying PD date will be current anytime soon. EB2 India has not been moving since long time. I am on H1b

In the I-485 application, who is primary and who is dependent? You can call USCIS and ask them the current status of your application. They would be able to tell you. If not, you can take a infopass appointment and they will definitely be able to tell you more details about the I-485 application.

Husband is primary and am dependent. What is info pass appointment. About calling USCIS I just have receipt number on the biometrics appointment. Can I use the same number and ask them the status of my I485?

Info pass appointment is where you meet with them face to face. http://infopass.uscis.gov/ When you call USCIS they would need few details from you (that only you would know) such as DOB, SSN, Alien number. Alien number can be found in your I-94 card, I-140 approval notice, etc. It starts with letter A. You can find all USCIS contact information in link below: http://www.mygcvisa.com/USCIS/USCIS-Contact.aspx
