Make sure your passport and visa are valid for the entire duration of your stay. Check whether your visa type allows multiple entries, as some visas require reapplication after certain periods abroad.

Keep documentation showing ties to Ireland, such as employment, school, or property, in case a CBP officer asks about your intent to return home. This helps demonstrate you won’t overstay.

Consider any pending applications or future travel plans in the U.S., as leaving while certain petitions are in progress can complicate processing. Consulting an immigration attorney before traveling ensures you take the right precautions.
