Emigrate to U.S?

In a word no.

Unless you have an American wife or husband or intend getting one the chances are almost zero.

If you have a specialties skill a US company may sponsor you for a visa. Or if you work for a company that has a US operation and they’re willing to transfer you.

If you’re from certain countries including Ireland you can enter the visa lottery for a green card.

The only other way I know of is to invest (I think) $500,000 in a business in the US.

Uscis.gov gives you all the information you need.
