I got my updated LOA. My studies will start on September 2021. The embassy is also requesting now my passport I already send to them my new updated LOA to the webform and to their email. My question is where do they base the validity of my visa because I heard it usually valid for only six months. If they give me an issuance that starts on december then i have to go their on June which I think its not advisable because its 2 months prior in my school intake.
