American and transatlantic firms in the UK
With many of the 'US firms’ in London offering training contracts, students looking for a City firm with a transatlantic twist have plenty of choice. There are roughly 100 US and transatlantic firms with a presence in the UK. Around half offer training contracts – they offer about 650 between them. The table below can be used as a starting point for finding out more about firms that operate in the UK market, having originated in the States.
By looking at Chambers UK, Chambers USA, Chambers Europe, Chambers Asia-Pacific, Chambers Latin America and Chambers Global you can track each firm's performance across the various countries in which it works. Our sister publication Chambers Associate gives detailed analysis of firms' reputations in the US recruitment market.
This table is split into two sections. The first part lists US firms that have opened up an office London and grown it from scratch, while the second part lists US firms that have entered the UK market via a merger with an established British firm. There are significant differences between the two types, which we detail below. Bear in mind that certain firms in the second category had their own office in London prior to merger (sometimes well established).

Working at an American law firm in London.
New office openings by US firms in 2016/17 included Florida firm Holland & Knight, which set up a small London outpost focused on aviation finance. Another transatlantic firm was born on 1 February 2017 when national firm Eversheds merged with US outfit Sutherland. In addition, international firm CMS is reportedly in merger talks with US firm Hunton & Williams. Meanwhile, US firm Winston & Strawn confirmed that it is recruiting two trainees this year, and Fried Frank has begun recruiting trainees for the first time.
Remember, while many of the firms below happily embrace the term ‘US firm’, others do not describe themselves as such, preferring the term ‘international firm’. You’ll get a sense of what to call them from the terminology used on their websites or from the True Picture.
Firms in the table below which feature in the True Picture have their name highlighted in red. Click the link to find out more. If the firm features in Chambers Associate, you can click the link "Read about the firm in the US" to find out about its activities stateside.

Part 1: US firms in London
These are firms with American origins that have opened up a brand new office in London, usually with the hire of just one or two partners at first, and grown it from scratch. Some (like White & Case or Baker & McKenzie) have been here for many years and are large and significant operations in their own right. Others (like McDermott Will & Emery or Vinson & Elkins) have chosen to remain small boutique operations, while yet more (like Locke Lord or Holland & Knight) only arrived on the scene recently.
Pros: Often smaller and more intimate; salaries tend to be higher to match New York market; no merger-related culture clashes.
Cons: The firm needs to break into the UK market and find a place in it, and it can take ages to build up the office (assuming management in the US even has the desire to do that).

Part 2: Firms created through transatlantic mergers
These can be either a large firm taking on a smaller one specifically to gain a London office (as with McGuireWoods' absorption of Grundberg Mocatta Rakison), or two of a similar size combining to form a larger one, with better global coverage the goal (as with the Hogan Lovells or Dentons tie-ups)
Pros: New firm has ready-made UK client base and established reputation; culture of legacy English firm usually remains post-merger.
Cons: Mergers can breed ill-feeling due to unforeseen culture clashes or if US headquarters starts to dictate to London office from afar.
