Second, write more and often and post many and many interesting things on your domain. If your website is not a blog add one, either as a category or a subdomain. I recommend the category option.
Third, post your links on social media like Facebok. Twitter or Reddit. You can pick which social media platform because, in some degree, it depends of your's website subjects and posts. Have in mind your target audience and be unique when you are writing your posts. You may copy ideas not texts.
Forth, you better search USA websites and blog and start commenting on them if you can. You may not get many dofollow backlinks but you may get visitors that read and like your comments.
If you have a good hosting provider for your domain the place where the servers are locates is not so important but having them in USA may help you especially when you have big traffic from your area.
Make content focused on the target audience of USA. For example, Donald Trump has been found guilty a few weeks ago (at the time writing thid words) then somebody tried to kill him. The second subject is still hot enough to get some atention from Americans especially the ones voting this November for the USA president. The violence is bad but you can get people attention if you write good enough about the hot subjects.
Have a good SEO and try to optimize it for keywords hardly searched in USA. You can also get backlinks from high domain authority sites present in that country.
Let's say these ideeas are enough for the moment if you want to start getting traffic from USA. With time you will get more and more experience and you'll find or have more ideas about this subject.
