I was supposed to enter via Honolulu but my flight got cancelled so I was rebooked via San Francisco.
Took me a total of about 5 minutes with the customs guy. He was super excited that it was my first entry on my green card. Explained that since we have been married less than 2 years I'd be CR1 and will have to remove conditions within 90 days of my expiration etc. Asked if I have more than 10k cash on me and confirmed the address for my green card to be sent.
I had 4.5h layover in SFO and it was way too long. Customs, rechecking my bags and going back through security took at most 45 minutes and the terminal was close so I didn't have far to walk.
Overall it was a great experience.
