Thank you for your reply..I also talked with our lawyer who did the process for H visas..She said you have nothing wrong that will let them deny your green card..Your status is good in US. She said if they deny for any other reason like not complete documents , they won't cancel your h4..It is apart from green card then..But she said your police records and any other things are fine iN uS..Your husband works leally here and you are legal here..So she said h4 wont be a problem..
