Owing allegiance is consummated by Oath. There is no other way for it to be on record.
An American citizen does not necessarily owe allegiance but they are subject to the laws. If a citizen commits a treasonous act, they are either guilty of sedition, subversion, or treason depending on whether they owe an allegiance or not. And there is no way to prove an allegiance duty other than to find a record of an oath taken. Otherwise, it becomes one word against others, a misapplied interpretation, a misunderstanding, etc.
My contention is that "owing" is not the same as "affirming," and that a citizen who has not sowrn an oath of allegiance to the US can be charged with treason. See Tokyo Rose, born in the US, not naturalized.

What is the support for the contention that a US citizen does not, absent taking an oath, owe allegiance to the US?
“Owing allegiance is consummated by Oath.”
This is why *I* believe at this time every federal employee should be required, as a condition of employment or maintenance of employment, to stand before a judge and pledge allegiance to the United States.
