Welcome to the forum

Is an immigration lawyer recommended for this process, and if so I would be grateful for recommendations.
Not usually - if you have a straightforward situation (your wife doesn't have any serious criminal convictions or bad UK immigration history), then a lawyer is not needed at all.
All the information you need to know about the visa process, the requirements and the documents you need to send can all be found for free on the UKVI website and here on the forum.
There have been several instances where people have hired lawyers and then those lawyers have given them very bad and incorrect advice, because they are simply not familiar with how to apply for a spousal visa from the US.
On the other hand, here on the forum we see people applying for spousal visas from the US every single day, and have been giving advice on how to apply and the documents required every day for years. We know the visa rules and the UKVI website pretty much off by heart
.
So, my advice, unless she has very complicated circumstances that give you a very real reason to believe she would be refused a visa for the UK and therefore would require a lawyer to argue her case, there's no need to waste your money on an immigration lawyer

Feel free to ask any and all questions you have about the process here on the forum
