I am a US citizen and have an opportunity to stay with a friend in Ireland starting in August. I'd like to be in Europe for 4.5 months, Ireland as my home base. My very rough plan is as follows:
August - Ireland 2 weeks, England 2 weeks
September - Ireland 2 weeks, Belgium 2 weeks
October - France 2 weeks, Italy 2 weeks
November - Italy 1 week, Switzerland 1 week?, Ireland 2 weeks
December - Ireland 2 weeks
I have a one-ticket from Boston to Dublin for August 4th. I know I need to get a return ticket back to the states but it won't be until mid-December (more than 90 days after I arrive). Should I also get my tickets to the other countries I plan on visiting ahead of time so I can prove I won't be in Ireland the entire 4.5 months upon arrival? Will I be denied entry back into Ireland after 90 days? Am I supposed to register with the Garda Immigration Bureau and get an extension for 3 more months (I can prove I can financially support myself)?
Thanks for your help!!
