The Commonwealth is made up of states that gained independence from the British Empire since 1947 and any other state that is given permission to join such as Mozambique. One of the criteria is that members must accept the King/Queen of the United Kingdom as the head of the Commonwealth.
There's quite a few different factors. At the time America gained independence, the Commonwealth hadn't been established, as Britain still retained all of her other colonial possessions. America could never have been a Commonwealth Dominion for a couple of reasons. First, America was established as a Republic, which automatically made the country ineligible to be a Dominion. Second, after fighting a long war for independence, the American public wasn't going to accept the idea of having to accept the British monarch as head of state still. Going further, when the terms were negotiated with Britain, France - who had supported the US in the war for independence - had to be appeased, as well, and retaining ties to the British monarch would not have accomplished this.
Relations between the US and Great Britain really weren't that hot in the following years. There was the War of 1812, there was British support of the Confederacy, there was the issue of the British impressing American sailors and forcing them to serve on British vessels, which went all the way up to the First World War.
On top of it, after the Suez Canal Crisis, the positions of America and the Soviet Union as the world's superpowers was firmly established, and, at that point, there was no way a superpower was going to make itself part of an organisation which made it subordinate to a non-superpower.
America has also seen a heavy influx of Irish immigrants, who certainly would've objected to membership in the Commonwealth.
In all, there's a number of reasons, but the biggest factor is probably just when independence was achieved.
Guyana is a member of the Commonwealth of Nations (since 1966) and is a country in South America.
