Hi,

Based on http://www.bluecard-eu.de/eu-blue-card-germany/, the minimum gross salary to get EU Blue Card is 46,400 Euro per year.

My question is as follows. Assume that someone has been working since few years ago in Germany. Now if he or she wants to appliy for Blue Card in the middle of the year and let's say end of June for example, then how do they know how much the gross salary by the end of the year will be?

Do they look at the sum of the gross salary from the beginning of the same year until end of June and divide it by 6 (number of months from January to June) and multiply it by 12 (to translate it to the gross salary of the whole year)? 
If so, the Weinachtsgeld will be missing then.

Or do they have a way to ask the arbeitsgeber about the gross salary of the whole year?

Or may they look at the last one year salary, no matter if part of it goes back to 2012? 

Please leave comments if you have any information about this.
Thanks,
Sara

They asked me the job contract only.

Since you are supposed to inform them about changes of contract or employer , it makes sense.
