how to file as part-year resident alien for federal tax return

[tax1111]

Taxpayer left the country in June 2020 permanently. He was a resident alien based on substantial presence test for the period before he left and the residency status terminated when he left US. 

Does he need to file dual status return in this case? Since he has no US income after he turned nonresident, I assume he only need to file a regular federal 1040 to report his worldwide income before his residency terminated. Is that right?

Also, does he need to file 8938 to report foreign financial accounts assuming he had the reportable accounts by the time he terminated residency?

Thank you!
