Dear Asgardia official:

         because the constitution mentioned in Asgardia belongs to the constitutional monarchy, then I do not allow People's Republic of China citizens with dual nationality, so JIANFANGZHOU to submit formal official exit application, Asgardia volunteered to give up citizenship.

Hello ZHOUJIANFANG.

 We're sorry to see you go. You can complete your request to withdraw your citizenship in your profile which you can find in the top right hand corner of the main Asgardia page. If you require further assistance please email citizens@asgardia.space. 

We wish you well in your future endeavors.

There is no where to withdraw on profile page.
