Just to give some additional information but there are many government jobs or government contracting jobs where you can be a dual citizen, including I believe this one.
>>confid+(OP)
I didn’t mean lacking the exact same job opportunities, but having their loyalties be questioned and denied from certain secure positions.
I don’t believe this job actually would be possible as the level of clearance requested is usually denied to dual-nationals (without renouncing, of course).
