going to school internationally, then wanting to practice in US

so I'm a US citizen browsing through some international medical schools to apply to- I heard there is additional paperwork, headaches and hoops to jump through to practice in the US if you go to an international medical school... can someone send me a link of what those additional steps are? Thinking Europe, Australia, or Caribbean in addition to Canada, which I know is an easy transition to the US (but difficult to get into).. 2) does this include the big 4 Caribbean medical schools? 3)... going to school internationally, then wanting to practice in US
