Can Lodz students practise medicine in the US/Canada?

Hi,

I wanted to know if graduates (6 or 4 year MD and DMD) could practise medicine in the US or Canada? The reason I'm asking is because on California's board of recognized medical schools several Polish universities are listed along with their English division (example: "Medical Academy of Warsaw" and "Medical University of Warsaw (includes English Program)") but Lodz is not (it's English division).

If you can please let me know why Lodz's English program isn't listed, does this mean students can't practise medicine in the US? And if they can practise then why would the list explicitly mention the English division of other universities?

Thanks!
