1099/Incorporation allowed in EAD for dependant?

[VJ2017]

Hello,

Me and my spouse have our EAD/AP combo cards. My spouse is the primary GC beneficiary and I am the dependant.

My question is

1) Can I accept 1099 or create incorporation (LLC or S/C Corp) on EAD?

1.) Are there any tax implications using EAD and working for 1099?

2.) Any rules/laws that state EAD holders cannot accept 1099 and have to accept W2 from an employer?

Experts, please take a look and answer.

Apologies, if similar questions have been asked before.

Thanks.
