You can absolutely sell to the USA only. To do so, you will need to restrict your shipping to only be available for the USA. Here's how to do that once you have an account set up.
Go into Settings>Shipping.
From your shipping settings you will create zones for the areas you would like to ship to. Adding only a shipping zone for the USA and no other countries will restrict anyone from outside of the USA from checking out on your site. The result will simply show no shipping options for these clients.
If this sounds like something you may be interested in, here's also a really great guide to introduce yourself to drop shipping and starting a business.

Can you dropship to the USA whilst operating in UK and can you still continue to sell in the UK?
So can you sell in USA and UK at the same time?
I understand your concern but rest assured, you can totally dropship in the US even if you are based in the UK. Like others mentioned, you have to set your specific country restrictions within your Shopify backend. This will limit your customers to just those within the United States.
With this, however, finding suppliers who will be a part of your store will be another portion to think about. I recommend trying out Spocket, where you can get to explore a countless number of products from US/EU-based suppliers!
