Travel on AP. Issues, problems? Please help

[tik]

Hello,

I am currently pending adjustment of status (employment based I-485 on my wife’s job). I have EAD and AP. I am planning to travel for the first time since I came in the US on J1. After that I was on F1, H1, and now adjustment of status.

My questionas are:
1. Have anyone experienced any problems coming back into the US? If yes, why were they denied entry?
2. I hear some people were denied entry because they worked without an authorization, is that true? I never did, but my EAD’s are so confusing timewise that I am afraid an officer may make a mistake.
3. Would the fact that my wife is the main applicant ( I will be traveling alone) be a reason that I can be denied entry?

I appreciate any input. Thanks
