We are Indian Citizens on H1..

My wife/kids traveled to India for vacation in end of May 2018. My wife traveled back alone twice for her office meetings (1 week short trips). Last depart from US was 10Sep2018 (kids were in India with grandparents enjoying long vacation). Due to health reasons, she could not come back in Sept. Kids started going to school in India so everyone will travel back in May 2019 only.

I was in US entire 365 days of 2018 (primary).

For tax filing purposes, should I SAY for family lived with me entire year? Kids lived with me entire year?
