This is something that’s very poorly named.
You do not need a Travel Card to work in another local’s jurisdiction.
With a Travel Card, you are becoming a member of another local. You would do this if you’ve permanently moved to within the receiving local’s jurisdiction.
A better name for a Travel Card would be Transfer Card because you’re transferring to another local and becoming a member of that local.
When you request a Travel Card from your current local, you will need to have your dues paid 3 months months in advance to cover the period of time that it will take to process.
If you are a member of 993 and you drop a Travel Card into another local and you’re accepted, you will no longer be a member of 993. You will be a member of the local where you submitted your Travel Card.
To have your Travel Card accepted by 993, you will need to have lived in our jurisdiction for 1 year.
