Union apprenticeship sign-ups near Seattle - what worked for you?

The training centre near Seattle opened applications for apprenticeships in electrical and welding trades. I am in Seattle, in case local advice matters. Applications close in 23 weeks. What do you wish you had known?

Visit the training centre in person if you can. Seeing the classrooms helped me decide.

You earn while you learn, but the first year is tight. Plan your budget carefully.
