You seem to be asking some pretty basic questions both here and on other threads.
Perhaps your first action should be to do some personal research - for example immigration requirements for each country, perhaps a LinkedIn job search for the locations in those countries you are interested in etc.
Once you've done that you will probably find you have more specific questions people can help you with.
Good luck - remember.....Google is your friend!
