目前雇主公司要被收购，母公司名字理论上要变化了，公司都是大规模的知名公司，Tier 2 General 工作签证是否要通知HO这一变化？是否要变化雇主License甚至重新申请签证？
多谢！最好能有各条例的原文和出处。
建议你查下TUPE transfer，查明白后，来给大家普及一下啊
条文我就不去找了，在ho的网上去找guide，但是之前找过，新公司28天内递交license的申请即可
谢谢了，可惜TUPE是一般法务范畴上的雇佣合同的转化。不是和签证特定相关的。
多谢提示，找到具体条文了：
If your sponsor is taken over
If your sponsor is taken over by another organisation and/or there is a transfer of employment, the new employer must apply to become a licensed sponsor within 28 calendar days of taking over the business.
If your new employer does not apply for a licence, we will limit your permission to stay to 60 days. You may want to apply for permission to stay with another sponsor. We will not limit your permission to stay if you have less than 6 months left.
If your new employer does not get a licence, then any certificate of sponsorship they issued is invalid.
不过还有个问题是这个28天的“taking over the business“具体怎么算，是并购的completion date吧？（不是announce date或者其他啥的）
按http://www.ukba.homeoffice.gov.uk/sitecontent/applicationforms/pbs/tier2-guidance.pdf，很明确如果TUPE适用的话，就不需要申请变更雇主事宜。
- A change of employment application is not required for other changes to your job. For
example if:
• you are remaining with the same employer and change jobs to a different job within the
same SOC code, or you are moving under TUPE (or similar) protection due to a takeover,
merger, de-merger or any other circumstances in which TUPE is triggered.
不过那上面那个28天的适用于啥情况？仅适用于非TUPE的merge，或者新雇主没有license？
是completion date的，不可能是announcement date，那个时候legal entity都还没有变呀
