My lawn landscaper asked me to check the internet to see if his work visa could be denied for renewal:
Anger management... dui... multi-traffic violation... insurance fraud by registration
Car in a state to not having to pay higher ins. Premiums. He has driver's license in the state he live's and works for the past 5 years.

He has committed some crime and has been ordered to take anger management ? He has had a DUI, has had a lot of traffic tickets, and has been convicted of insurance fraud ?

Sounds like enough to cause it to be denied.
