What should I expect through the process of reclassifying to 11B, getting to my unit, and opportunities?

I have submitted a conditional release to get out of the reserves as a 42A, and go infantry as an 11B. What should I expect through the process of reclassing, getting to my unit, and opportunities. I am already promotable and am aware I will lose that status, but would I have to wait a year? Three years? Thanks in advance!
