Number eighteen of the Decree on the Appropriate Renewal of the Religious Life reads that it devolves upon superiors to see that the "best persons" are chosen for "professors" and that they are to be "carefully trained."
If you feel your call is to study in Rome, then feed your superior this line in your begging letter:
"Throughout their lives religious should labor earnestly to perfect their spiritual, doctrinal, and professional development. As far as possible, superiors should provide them with the opportunity, the resources, and the time to do so."
