A work permit application in the UK could take up to 24 weeks at the moment. Depending on what sort of work permit is applied for the waiting time could be reduced to three weeks.
Employers seeking to hire foreigners under the Highly Skilled Migrant Program (HSMP) can expect to wait the longest, maybe even as long as 24 weeks. A Leave to Remain application could take up to 10 weeks to process.
The fastest applications at the moment are the Worker Registration Scheme, but they can still take up to three weeks.
