Welcome to immigrationboards.com!
It depends when their tier 2 visas expires and when they could return to the UK.I believe they were on a Tier 2 visa originally before lockdown and returning to Japan, if the company extended their contract by 6 months could they continue to work under their Tier 2 visa or would they need to apply for a Tier 5?
What is their job exactly? Is it a creative/sportsperson job?? To be sponsored for a tier 5 visa, you can only work your contracted hours for your Tier 5 sponsor. It is also not 'shortage occupation work for 20 hours'. The supplementary employment must be in the same sector and same level as their main job.If they did apply for a Tier 5 creative/sportsperson, would they be able to work in a shortage occupation? I saw on the .gov site that workers are allowed to work in shortage occupations for up to 20hrs a week but our contracts are 35hrs.
do a second job in the same sector and at the same level as your main job for up to 20 hours per week
That is an option and they can work for any employer on this visa.Would they be better to apply for a Tier 5 YMS as they are both between the ages of 18 and 30 and from Japan? The only issue with this is the large savings required and I don't know if they have that money available to them.
