i 485 - wife's name not included

[immihelp]

1. You can include their names any time before your I-485 gets approved. As you will not know exactly when it would be approved, you should add them as soon as possible.
2. Around 4 months.

Hi,

My PD is current. I am going to apply for I-485. But, I am not planning to include my wife and child's name due to some reasons.

Can I include their names at a later stage? If I do not include their names what are the repercussions.

How long will it take to get EAD after applying for I-485?

Pls reply.

Thanks.
