Processing times for work permits have not changed much over the last month. A work permit application in the UK takes up to 5 working days.
Applicants under the Highly Skilled Migrant Program (HSMP) can expect to wait the longest, maybe even as long as 26 weeks.
If you are in the UK already on a work permit or under HSMP, you will probably also have to submit a Leave to Remain application which could take up to 13 more weeks to process.
Worker Registration Scheme applications for nationals of the new EU Countries can take up to 3 weeks.
