Resident vs Non-resident Alien

Hi, I entered the first time the US with a j-1 student visa in December 2015, I was in the US until June 2016. This visa expired in July 2016. Then I moved to England and I came back to the US in May 2019 with another J-1 Student visa again for Ph.D. So the problem is I didn't change the type of my visa, I entered more than 5 years from now and I was in the US for more than 183 days with two different J-1 Student Visa. Should I prepare my tax return as a resident alien or non-resident alien??
