You're fucked up, since you've written that you're "planning to move to US.", if you try to put foot there, you'll be rejected and flown back right away.
All you can do now, is the queue at the nearest US ambassy to try to get a green card. Without that, don't by a flight ticket to the US, it'll be lost money and time.
Speaking from personnal experience.
My advice: keep working remotely. Use Skype for meetings.
Having no experience with US immigration on this matter I don't know how likely it is that they'll see it, but it's probably a very good idea for the OP to nuke this topic if they can.
Meetings are fine, but if it can be proven that you intend to work illegally (which AFAIK,IANAL anything more than meetings would be) you can potentially run into serious trouble.
