Ari, glad to see you here.
You will have whichever status you earn until January 31, 2018.
However, if you wait until January 2017 to earn it, you will have it until January 31, 2019, so you might want to delay it if possible.
If you're going for Seven Stars, I would definitely wait until the beginning of the year before you start earning it, as your tier points go back to 0 on January 1 each year.
