Hi @61549242 ,
Thanks for reaching out.
Just like general Azure AD federation, B2C allows to federate user accounts from Azure Gov cloud as well.
Refer to integrate Azure AD with B2C - https://learn.microsoft.com/en-us/azure/active-directory-b2c/identity-provider-azure-ad-single-tenant?pivots=b2c-custom-policy
However, there might be compliance issues to allow gov employees to commercial applications.
Hope this will help.
Thanks,
Shweta
