This is the highest number of American citizenship applications in the UK that has been measured for a period since the measurements began - and it is an increase of 12 percent compared to the previous quarter, the statistics show.
Political uncertainty in the US is behind many applications, according to immigration lawyers who work with membership applications.
They are leaving due to anxiety, frustration and to gain financial security. But beyond that, there is also a deeper concern about personal security, says Ono Okeregha, head of the law firm Immigration Advice Service.
The statistics also show that applications from Americans for student visas in the UK increased by nearly 10 percent during the period compared to the same period last year, a development that is partly linked to the Trump administration's conflict with top American universities.
The American applications contributed to lifting the number of applications for citizenship to a record high of 72,729 during the first quarter of the year.
