Canadian citizen marrying an H-1B holder — looking for advice

Looking for advice from anyone who has been in a similar situation.

What is the process for a Canadian citizen to move to the U.S. after marrying someone on an H-1B? Are there any Canadian-specific considerations around entry, status, timing, or the overall immigration process?

Also looking for recommendations for U.S. immigration attorneys who have experience with H-1B + Canadian spouse cases.

Would really appreciate any firsthand experiences or recommendations. Thanks!
