Hello tranthidung. I spotted a small typo in the OP, as it follows:
1. November 22, 2009 - January 22, 2018: Without activity requirements
[...]
2. June 18, 2013 - January 23, 2018: Activity requirements
[...]
3. January 24, 2018 - by now: Activity requirements + Merit requirements
I think that first period should be defined as "November 22, 2009 - June 17, 2013" instead of "November 22, 2009 - January 22, 2018", as the second stage starts with June 18, 2013.
