Do Irish people born in America have to visit Ireland in order to be Irish?

Somalian, Afghan, Sudanese , Ireland is black now

You could have fifty stamps in your passport from visiting Ireland and it wouldn't make you one one-thousandth of a percent Irish. Why don't you idiot yanks get that through your thick noggins already? You desperately want to identify as being part of something that you're not. To us, you're about as Irish as the Rongorongo script. We ought to make it a requirement for all Irish Americans to pass an intelligence test to call themselves Irish. Guaranteed these stupid questions would disappear the next day. Jaysus you people are bungalows of the first order. 

They can visit any place that will let them in.   Try Disneyland.  Plastic paddies are a source of money and amusement for the Irish.

If you are an American citizen, you can call yourself Irish while in America. Unless you were born in Ireland, or have lived there for much of your life, you are not considered Irish in Ireland or in Europe generally. There's a difference in meaning in the word in the US, where it refers to one's heritage and ancestry while everyone around is assumed to be a US citizen; however in European countries including Ireland itself, you would be considered an American of Irish ancestry, and not Irish. 

If you're born and raised in the States? Then you're a Yank. If you're born and raised in Ireland? Then you're Irish.  It's as simple as that. 

People BORN in Ireland are Irish. People BORN in America are American. Your ANCESTRY may include Irish, but that doesn't make you Irish; neither does visiting. You can't become a citizen of any country by merely visiting. 

Individuals brought into the world in the USA are American, perhaps they have Irish family so most "Irish-Americans" who case to likewise be Irish are not, just in the event that their parent/s or grandparent/s are lawful Irish nationals then they could apply to likewise turn into an Irish natioanal.

For somebody to be a public of Ireland they don't need to visit Ireland however they do should be lawfully enlisted as an Irish public and they are still Americans in the event that they visit Ireland utilizing an American visa

they have to speak Gaeilge or Hiberno to be ethnically Irish

I'm not sure what the legal requirements for the nationality (being legally Irish) are

Born in USA, one is American. Irish background (of which I have) does not make me Irish any more than French, Czech, German and any other ethnicities I can conjure from my relatives. I am American, as are you. Were you to move to Ireland, get citizenship there, and all the happiness of red tape or marriage which led to your being allowed to live and work in Ireland, yhen you could truly say "I am Irish"... without "descendant".

People of Irish descent born in America are no longer Irish (although they may be able to claim a passport) - they're American of Irish descent...
