Hello dear engineer. I want to know, which load combination i need for use when I check serviceability limit state using seismic load.

RE: ASCE SLS combination for seismic
Different drift limits apply if you're doing extra-code design such as performance based design but that, then, is another kettle of fish and much is left to the discretion of the design team.
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Design based on ASCE 7-10 in the US gives you some "help" by removing the CuTa cap on your building period. So in a way, it is a sort of "serviceability" check (though not labeled as such).
You check the non-period-capped drift against Table 12.12-1 and the exceptions/notes in Section 12.12.
