Your local University will send you a link for the polish embassy. In this link there will be 2 visa options. National Visa (choose this option) or Schengen Visa(this is normally just for tourist). From here refer to the checklist shown and prepare the online application form before printing it out and submitting it together with the relevant documents mentioned in the checklist to the polish embassy located at the Office tower of Wisma Atria lvl 17. It takes about 2 weeks although exceptions can be made if you are in a rush
