最新PBS Dependent申请ILR政策变化，如下是其他论坛总结的精华，我和UKBA网站新移民法核对过，且有原文出处。
总的来说：
1）2012年7月9号之前，你的配偶是granted leave to enter or remain as a PBS dependant before 9 July 2012, 如果你的配偶满足和你在英国连续生活2年，你的配偶就可以直接和你申请永居（填表格 SET（O））。
2）2012年7月9号之前，你的配偶是granted leave to enter or remain as a PBS dependant before 9 July 2012, 如果你的配偶不满足和你在英国连续生活2年，但是其可以在dependant 签证到期之前够连续生活2年（之间可以允许不全是dependant签证），之间你的配偶可以不需要更换签证，虽然主申请人已经获得了永居 （原文：The amended rules allow for a PBS dependant to qualify for leave to enter or remain and to complete the route to settlement, provided they remain the partner of the same person they entered this route as the partner of, without having to switch into the category of partner of a settled person provided the main PBS migrant gains settlement on this basis, or gains British citizenship following a grant of indefinite leave to remain as a PBS migrant.）。当你的配偶到了够2年的日子，你的配偶就可以直接申请永居（填表格 SET（O））。
3）2012年7月9号之前，你的配偶是granted leave to enter or remain as a PBS dependant before 9 July 2012, 如果你的配偶不满足和你在英国连续生活2年，在dependant 签证到期之前不够连续生活2年，这时候你可以在签证到期之前申请further leave to remain under paragraph 319C (b) (iii) (1), 可以给你3年的时间还是 PBS Dependant，而且可以续申请（如果你愿意的话），这期间，如果你的配偶满足和你不间断连续在英国生活2年（包括absence day），你的配偶就可以直接申请永居（填表格 SET（O））。在这期间，你的配偶可以有另一选择，不过傻子才会选择， 那就是 “switch”到spouse visa (表格 FLR(M))，spouse visa 比起上述比较麻烦----还需英语证明。
4) 2012年7月9号之后，你的配偶是granted leave to enter or remain as a PBS dependant after 9 July 2012, 如果你的配偶不满足和你在英国连续生活5年，在dependant 签证到期之前不够连续生活5年，这时候你的配偶可以在签证到期之前申请further leave to remain under paragraph 319C (b) (iii) (1), 可以给你3年的时间还是pbs dependant，而且可以续申请（如果你愿意的话），这期间，如果你的配偶满足和你在英国生活5年（必须是dependant，包括absence day），你的配偶就可以直接申请永居（填表格 SET（O））。同样存在选择 “switch”到spouse visa (表格 FLR(M))问题，一般人不会选择这个。
5）特别强调， 永居主申请人如果是 十年Long Residence（最后一个签证虽然是PBS），但是你的配偶PBS dependant partner will not be able to extend their leave or gain settlement as a PBS dependant and will be required to switch into the partner of a settled person category and apply for limited leave. 你的配偶必须转成spouse visa.

Dependants of PBS (Tier 1 General, Tier 2) migrants
Spouse / Partner
-
The dependant is subject to qualifying residential period to be eligible for settlement. For the duration of qualifying residential period and associated conditions that may apply, see Note below.
-
If the dependant has completed the relevant qualifying residential period at a time that the principal migrant applies for settlement and meets the other requirements then the dependant may be included in the principal migrant’s settlement application.
-
If the dependant has not completed the qualified qualifying residential period at the time that the principal PBS migrant applies for settlement, then:
a) If the PBS dependant’s current leave will expire after he/she has completed the qualifying period and the dependant meets the other requirements for settlement then the dependant may apply for settlement directly (319E).
b) If the PBS dependant’s current leave will expire before he/she completes the qualifying period then the dependant can apply , before his/her current leave expires, to extend his/her PBS dependant leave until such time that he/she becomes eligible for settlement (319C and 319D). Though switching to FLR(M) leave remains an option but extending PBS dependant leave is simpler (e.g. - only maintenance funds to be shown, no English language requirement).
c) Doctor / dentist dependant with employment restriction - For PBS dependant who is a doctor / dentist but does not satisfy 319D(b)(iii) should consider switching to FLR(M) at the earliest opportunity to become free from the employment restriction, instead of continuing on PBS dependant leave.
Note:
Entry clearance application as PBS dependant submitted before 09-Jul-12: The PBS dependant will always be subject to rules in place before 09-Jul-12. The PBS dependant must have lived with the principal PBS migrant in the UK for at least 2 years in a marital relationship, civil partnership or in relationship akin to marriage or civil partnership (319E(d)(i)). This “2 year” period need not be as a “dependant” and need to be “continuous”. *** Probably unchanged? *** These requirements and conditions apply both when extending leave as PBS dependant (319E(d)(i)) or if switching to FLR(M) leave (287(a)(i)(d) or 287(a)(i)(e)) any time during the 2 years period to become eligible for settlement.
Entry clearance application as PBS dependant submitted on/after 09-Jul-12: The PBS dependant will be subject to the new rules introduced on 09-Jul-12. The PBS dependant will be eligible for settlement only after completing 5 year probationary period as a dependant of the principal migrant (319E(d)(ii) or E-ILRP.1.3.). This “5 year” period need not be “continuous”.
请高手指正，如果有理解不正确的地方。谢谢。
