Marrying in the US

My English fiance is coming to the states for our wedding next month. He'll return home afterwards and I'll apply for the spousal visa. He'll have a return ticket of course and he travels on the ESTA, but will he need any more documentation (such as a letter from his employer stating when he's due back at work)?

My (now) husband didn't need anything else when he flew over to get married and for a visit. The ESTA takes care of proving that he has strong enough ties to the UK to need to return at the end of the visit.

Depending on your location, he may need to bring over a long form birth certificate to apply for the marriage license. I'm from Stanly County, NC and that's all that they required from people without a NC drivers license. Give your local registrars office a call and see if they need anything in particular to process the marriage license.

Also, congrats! 

The less the authorities know the better, in my experience.

We didn't need any other documentation when my British husband came to the US to get married.  I would make sure you had his long, detailed birth certificate just in case.

GOOD LUCK
