Ask an Immigration Solicitor. Get an Answer ASAP.
Thank you for the question. It is my pleasure to assist you with this today. I will revert back shortly with an answer to your question.
If you arrive into the UK on your current visa you will then need to make a change of employment application in order to work for the new prospective employer. If however, you do not travel on your current visa then you will need to submit a new skilled worker application. As your partner will already have dependant leave they will not need to re-apply if they are already in the UK.
Can I help with anything else today?
Yes once your second visa gets approved the first one will be cancelled. If the application is refused the first visa will not be valid as the second visa will override the first visa as there is a change of circumstance.
It’s best to inform the first company that you no longer wish to take up the employment as they will need to report this to the Home Office as apart of the sponsor reporting duties.
