You can bring your dependents or your spouse along with you:
1) When you first travel to the UK on a tier 2 work visa.
2) When you have passed your OSCE- the second part of the NMC examination.
If you hold a Tier 2 General visa you can bring your dependents with you while you work in the UK so long as you do not require access to public funds (for example child benefit which is rare cases). While here the candidate’s dependents can also access the National Health Service (NHS) and State Schools for free just as any other UK resident would. Since the applicant is coming to the UK as a pre-registered nurse most of the employers recommend bringing your family after passing the OSCE examination or maybe a few months after you arrive in the UK. This is to enable a smooth settlement in the country.
Applications by Tier 2 dependents / Work Permit dependent can either be at the same time as the main applicant or at a later date if required. Dependent visa applications are granted in line with the main applicants leave to remain.
