Do I have to register my brand in the USA to start with SPACEGOATS?

No, we can also use all the benefits of the Brandregistry with your trademark registered with DPMA or EUIPO. You don't have to register with the USPTO for that. However, if you aim for the recommended legal trademark protection, it makes sense to start the registration process early, as it takes between 12-18 months. Please see the article 'How can I add kdglobalusa to my Brand Registry?' to add us to your Brandregistry.
