Thanks. There is a distinction made between spouses who are non resident aliens and resident alien/US citizens however.
The IRS website you quoted goes on to say:-
"You are considered unmarried for head of household purposes if your spouse was a nonresident alien at any time during the year and you don't choose to treat your nonresident spouse as a resident alien. However, your spouse isn't a qualifying person for head of household purposes. You must have another qualifying person and meet the other tests to be eligible to file as head of household."
Based on this, I should qualify as HoH.
