Anyone in NYC? I'm at 8.5 months now and waiting for the interview.

On other note, I'm starting to think about sponsoring my parents. If changes to "chain migration" do not occur and I am given the chance to sponsor my parents once I become a USC, what roadblocks do they face? Does working without an EAD, having a license from another state, not being in good health affect their chances? Do they need to interview or anything
