Filing Status Question

Should I be using 'Single' or 'Head of Household' status?
My father became a US a resident in June 2024. Non-resident until June 2024 and living abroad. He lived with me in NJ from July through end of 2024. He has no income in the US, however, gets pension and interest/dividends abroad. If I consider his foreign income only for the time he has been resident of US, it will be less than $5000. Can I consider him as my dependent and file my taxes as Head of Household or should I file as Single?

Thank you!
