Good luck with it! I went through the visa process with my (US) wife and we lived there for a year and a half before moving to the US - the process was much faster, almost all online, just had to mail her passport and a few supporting documents to the office in NY - six weeks later we had a visa in her passport, and a pink Biometric Residence Permit (UK version of a green card) waiting for her in the nearest main post office to our home. Nothing like the US process, for us at least: just proof of our marriage, having enough money to live on, and paying the NHS surcharge for the two years.
