I’m an Egyptian citizen living in Egypt, and I have an interview for a job in Austria. For reasons that are beyond the scope of this question I might not be able to get an HR letter from my current employer by the time of my application submission appointment. I do have the financial means to support myself during the duration of my visit, and I have a previous traveling record in and out of the Schengen area. My question is, do I still need to submit an HR letter to the Austrian Consulate in Cairo? or would I have zero chances of being granted a visa without any proof of employment?
