The IEEE-USA, i.e., the United States branch of the IEEE, has in the past lobbied against visas for high-tech workers. They seem to like rather reactionary policies. I long dropped my membership for that very reason. The ACM and USENIX are much better anyway.

Import your mail from Outlook into Mozilla for Windows. Mozilla stores all email in the mbox format, which is easily imported into Apple Mail. You obviously still need to transfer the files to your Mac, but that should be easy. Look for the mbox files in C:\Documents and Settings\user\Application Data\Mozilla\Profiles\default\some weird string\Mail.
