Motivation to Move to Germany

Hallo, hope everyone is having a great day. I just want to ask if its okay to state that my goal for applying for a Language visa is the Nursing Ausbildung? I am going alone to study language for 1 year and my wife will be left in our home country so I can state that as my proof of rootedness and that I will go back. I just want to ask if its okay to state that learning language is my stepping stone for the ausbildung since my aunt who will be supporting me is also a nurse. I appreciate everyone's time and input on this. Danke!
