Mid-American Carpenters Union

Hi! This is my first time posting in this subreddit. My husband is looking to join the Mid-American Carpenters Union. He took construction classes at a community college and has many certificates and is a very hard worker. I’m wondering if anyone has advice on getting sponsored in the union or if anyone knows any contractors? He unfortunately missed the deadline to apply into the union. I’m not really aware how much of this works and I’m just trying to help him out any way I can. Any advice is appreciated! Thank you!
