A focused set of questions for checking whether a company can realistically support your visa route.
Before applying, check whether the company sponsors your route, whether the role is eligible, and whether the advertised salary is likely to meet the relevant threshold. Ask about the specific role rather than asking only whether the company sponsors in general.
The best questions are practical and specific: ask about licence route, current sponsor status and rating, occupation code, salary band, Certificate of Sponsorship timing, whether sponsorship is considered for the role level you are targeting, and who owns the sponsorship process internally.
Do not ask employers to give immigration advice unless they are qualified to do so. Use employer conversations to confirm company-side facts, then verify route rules on GOV.UK or with a regulated adviser for case-specific advice.
Ask after you have shown fit for the role, but early enough that you do not spend weeks on a process that cannot support your route.
Confirm that the employer is licensed for the right route, the role is eligible, and the salary can support the relevant visa route.
