Unfortunately, currently we could assume nothing about the date. First card date definitely goes well. Application date … well, we have not seen so far any contagem de tempo for a GV holder that have application date in it.
While you do not need contagem de tempo in your application file by law, you could attach it, and most believe that it is better to do it. So in case we continue to be in a gray zone, I suggest that the best is to receive that contagem de tempo before applying. In that document you will see what date AIMA uses in your case. If you are wrong with your date and applied earlier than that, the application will be rejected and you will lose approximately 2 years of time. IRN will accept your application, they do not check at this stage if you comply with all conditions or not, it is all done at almost last stage. They will check if all documents in place, than send all requests to authorities, wait for replies, and only much later start checking the conditions.
You could apply again if something goes wrong, but you will lose lot of time.
But of course, you could apply even if your card is valid so 1 month, and deal with renewal later.
