For many lawyers considering a move between UK and US firms, compensation is often the most visible difference. In reality, however, the more meaningful distinction tends to lie in how firms operate day to day. These operational differences shape everything from daily responsibilities to long-term career development.
While Magic Circle and large international firms in London typically operate with sizeable trainee and associate cohorts, US firms tend to run far leaner teams. A Magic Circle intake might include 80 to 100 trainees each year. By contrast, US firms generally build smaller, highly specialised groups focused on premium transactional or disputes work.
As US firms have expanded their presence in the London market, many have also developed distinct niches, cultures and areas of strength. No two firms operate in exactly the same way. That said, there are several structural characteristics that tend to be common across many US law firm platforms in the City.
These operational differences can have a meaningful impact on how associates work, learn and progress.
Earlier Ownership and Responsibility
US firms typically expect associates to take ownership of their work earlier in their careers.
From the outset, associates are trusted to manage workstreams, understand the commercial objectives behind transactions and contribute meaningfully to deal execution. There is generally less emphasis on gradual exposure and more focus on being closely involved in the core of the matter from the beginning.
This approach can create a steeper learning curve, but it also tends to accelerate the development of both technical skills and commercial understanding.
Direct Partner Exposure
One of the most noticeable differences is the level of direct interaction with partners.
Rather than working through several layers of hierarchy, associates at US firms often work closely with partners or very senior associates. This can lead to stronger working relationships and earlier exposure to decision-making, client management and negotiation strategy than is typical in larger teams.
That proximity can provide valuable mentoring and a clearer understanding of how high-value matters are managed. It also means expectations around responsiveness, judgement and quality are high.
A Flatter Structure with Higher Expectations
US firms generally operate with flatter team structures and fewer layers of management. Associates often sit alongside partners and senior lawyers, creating a more integrated working environment.
For ambitious lawyers, this accessibility can be a real advantage. At the same time, it removes some of the buffer that can exist in larger teams.
The standard of work expected is consistently high. Attention to detail, responsiveness and commercial awareness are treated as baseline expectations rather than skills developed gradually over time.
A Different Environment, Not Necessarily a Harder One
It is important to note that working at a US firm is not necessarily harder. The structure and expectations are simply different.
The environment tends to suit lawyers who are proactive, commercially minded and comfortable working with a high degree of autonomy. Those who thrive often value the direct exposure, faster development and close involvement in complex, market-leading work.
For many associates, the move represents not just a change in compensation, but a meaningful step forward in responsibility, capability and long-term career positioning.
At Sonder, we work closely with associates considering this move, helping to explain how individual firms operate, what different teams expect, and which environments are most likely to align with each lawyer’s strengths and career goals.
