Comparison
Fragomen LLPvsGiambrone & Partners
Two providers, same data sources, same editorial standard. This comparison does not recommend either — it shows what the public record says about each.
World's largest immigration law firm. London office at 95 Gresham Street. SRA-regulated. Handles corporate immigration at scale — Italian citizenship by descent is a niche offering within their broader practice.
Established multi-practice law firm with offices in London and Italy. Handles citizenship by descent, marriage, naturalisation, and 1948 cases alongside property, succession, and cross-border disputes.
Strengths
Fragomen LLP
SRA-regulated with mandatory professional indemnity insurance, meaning there is a formal recourse mechanism if service falls short
The sheer scale of the world\'s largest immigration firm means access to resources, precedent databases, and institutional knowledge that smaller firms cannot match
Physical London office at 95 Gresham Street with in-person meeting capability, unlike many Italy-based providers who work entirely remotely
Companies House incorporation dates to 2006, giving nearly two decades of continuous UK operation and verifiable financial history
Giambrone & Partners
384 Trustpilot reviews is the second-highest volume in this directory, giving a statistically meaningful picture of client experience
Six offices across London, Milan, Rome, Palermo, Naples, and Catania means physical presence near most Italian courts and comuni
Over 20 years of history since 2004, through multiple generations of Italian citizenship law changes
A team of 50+ means capacity to handle volume without the bottleneck risk of smaller practices
Citizenship sits within a broad Italian legal practice, so cross-border property, succession, or family law matters can be handled under the same roof
