Home Secretary Suella Braverman has vowed to step up efforts to bring "crooked" immigration lawyers to justice.
It comes after reports some firms are offering to submit false asylum claims for a fee.
A new taskforce, which has been carrying out preliminary work for a few months, has officially been launched.
The Home Office said it would help build stronger evidence bases to support prosecutions.
But the Law Society said the Home Office was focusing on "a tiny minority of lawyers" rather than the "significant backlogs in asylum claims".
The organisation, which represents solicitors in England and Wales, said the necessary powers were already in place to deal with immigration advisers engaged in misconduct.
