Weezy arrived to the NY jail in a corrections van -- we're told because the rapper is a "high-profile inmate," he was not transported with any other prisoners.
As of now, we're told the rapper is still undergoing the admissions procedure at the jail -- which entails a physical & mental health exam & questionnaire.
It has yet to be determined whether Lil Wayne will be in the general population at Rikers -- or if he will be given his own cell.
And since moving can make any convicted felon hungry, the jail chef has the perfect dish for Wayne's first night -- noodles with beef sausage & marinara sauce, steamed greens, a mixed green salad, whole wheat bread, sliced peaches & a fruit drink or tea.
Weezy was sentenced to a year in the big house for a gun charge -- but he could be out sooner if he stays on his best behavior.
