My wife is considering applying for a new role within the organisation she's currently employed at, where she's worked for the past few years. We're aware that to meet the income requirements for my visa we must have been in our jobs for 6 months ahead of applying. Would her changing roles in the same organisation affect the eligibility of claiming this income for the visa requirement?
The requirement for category A is only that she must have been with the
same employer, earning at least £18,600, for at least 6 months... so if the new role is within the same company, and her salary has been above £18,600 for the whole time (regardless of role), and will still be above £18,600 when she returns to her previous role, then it won't make any difference.
They will take her lowest payslip from the last 6 months and multiply it by 12 to get her annual salary, so as long as her lowest payslip is at least £1,550 before tax, she will still meet the requirements, even if she's only recently started the secondment.
