Juelz Santana is staying grounded in New Jersey, a judge just denied his big trip to sunny South Florida -- this after the feds claim the rapper failed a drug test -- but his team believes it's a mistake.
According to new legal docs, the Dipset MC was asking for permission to fly down to Miami this month for work, but when he asked the court for approval, the feds said he wasn't fully following the rules of his supervised release, and a judge put the kibosh on the whole thing.
Remember ... Juelz is on supervised release after serving 19 months in prison as part of a 27-month sentence in his airport drug case. So, he has to get permission to travel outside NJ, and take mandatory drug tests.
In the docs, obtained by TMZ, the feds claim Juelz was planning to travel to Miami with 2 convicted felons -- a no-no under supervised release -- and the Assistant U.S. Attorney also says his recent urine sample tested positive for opiates and methadone.
Add it all up, and the judge ended up denying the request.
Juelz's attorney, Jef Henninger, tells TMZ ... Juelz will follow the rules for travel requests going forward and will hang out with "the right people." We're told his camp believes the drug test was a false positive.
