Do foreign internships prior to graduation in a different NOC count for total work experience in FSW?

I have 2.5 years full time work experience after masters in NOC 9999 in the US. It’s my primary NOC and my minimum one year requirement work experience.

I also have 6 months full time paid foreign internship experience in NOC 7777 from my undergrad in India from 4 years ago. I did this before graduation during my final semester.

Can I add both for a total of 3 years total work experience? Does it matter that the internship is in a different NOC and was prior to graduation?

Used example NOCs not actual.
