Seems like you are missing the most important info, how are you going to work and get a visa that allows you to do so? How much money do you have to keep you afloat while you get on your feet?
Ireland
Bills will be cut in half by having a roommate. A friend of mine completing his education is going to ireland in august and offered to have me as his roommate to cut our expenses in half. I'll be selling all my belongings here to get me started there. I have ancestry there as my great grandparents were immigrants from there. I still have some planning to do but this is my best chance at escaping my country and I would be foolish not to take it. So now I'm trying to make plans.
I won't have much but then again neither did my great grandparents. I will just have to make this work however I can. The good news is since I'd be in dublin, I should be able to get by fine without a car, which brings down costs even further. I'll have to roommate. I will have to do some networking and get a job lined up there from over here but I'm still working on that. Just tackle each problem one at a time.
I think US gets a 90 day travel visa for Ireland, so if you don't have a job that gets you a visa by then, you'll have to leave the country.
Another option could be trying to enroll in school and get a student visa. If you have a bachelor's, maybe a grad program.
If you are trying to do jus sanguinis citizenship you should do the research to ensure you have everything you need to prove it and begin the process because it will probably take longer than 90 days as well.
Getting additional education seems very unlikely since I cant afford it.
That requires grandparents. Great-grandparents are useless.
I've actually seen conflicting things about great grandparents for getting citizenship in ireland. I'm not really sure what to believe at the moment.
Great-grandparents are useless, it's unambiguous.
It looks like in the table on that site E would work for me but only if my mother registered me as a foreign birth before I was born?
