I just want to ask you that what if I want to promote the site for the USA. The same factor is applying if I want to promote site in usa

Yeah, it applies for all countries. In-fact for US you may apply also these:
1. Get US based server.
2. US based directories are more then any other countries, getting so listed in those are easy one.
3. Use stumbleupon. It will directly send you traffic and also get you well ranked.
