本人tier 2 7月中到期，现在拿到三个月的extension。
第一个问题是永居时间是从签证有效期开始还是入境日开始算，可提前28天申请。签证是01/09/2010签发，19/09/2010第一次入境，请问最早从哪天可以申请永居。
第二，按照目前的情况，大多数申请被推迟甚至中止，如果我申请延期在我现在签证过期之后还没有下来，到了我可以申请永居的时间可否直接申请永居？在官网上看到这个材料，里面说
Example scenario 1
An applicant submits application A in time. They then submit application B before
application A has been decided, but after the applicant’s leave has expired when the
applicant transitioned to 3C leave. As the applicant transitioned to 3C leave and a decision has not yet been made on
application A, application B is automatically considered as a variation of application
A. The date of application is the date application A was submitted.
如果申请日期按照第一个申请算，那永居是肯定fail的。
麻烦各位给出个主意，先谢过了。
