Dear member,
Thank you for contacting us.
Please be advised that section 4 (B) (ii) of IMBRA exempts dating
companies whose principal business is not to provide dating services
between US citizens and foreign nationals so long as it charges comparable
rates and offers comparable services to all individuals regardless of
gender or country of citizenship. Consequently our company is exempt as it
falls within this exemption (as do many other large dating companies).
Full information regarding IMBRA can be found at

I hope this info helps
