This is because I am not a US citizen and do not have a business presence in the US - so I appear to be restricted from registering it.
Is there any way around this?
I will not be building a website on the domain, if that makes any difference.
I don't think I could trademark KeywordKeyword - but I could trademark KeywordKeyword.com
If I trademark all the different extensions too, I would guess it is going to cost me a lot of money - I'm not sure if I could justify a major expense like that - and I'm not sure if it is really necessary.
At the moment, I'm just concerned with getting the domain space sown up.
As you don't do business in the US, does a .us domain really matter to you?
No, it doesn't matter to me - I just don't want a competitor to register it
AFAIK, KeywordKeyword.com does not give the right to KeywordKeyword.tv and so on. If you have a (unique enough) KeywordKeyword you could get a trademark and then you could claim protection for all extensions...
My name is a generic phrase - not a unique brand name
