287(a)(i)(d) has been amended to replace "Tier 1 migrant" with "relevant point based system migrant", but ....
It is the way 287(a)(i)(d) is written that makes me question if this technical change has indeed been implemented (note use of "and" (underlined)):
(d) the applicant was admitted to the UK or given an extension of stay as the spouse or civil partner of a Relevant Points Based System Migrant, and then obtained an extension of stay under paragraphs 281 to 286 of these Rules and has completed a period of 2 years as the spouse or civil partner of the person who is now present and settled here; or
Likewise, there is no change in 319E (note use of present tense (underlined)):
(b) The applicant must be the spouse or civil partner, unmarried or same-sex partner of a person who is, at the same time, being granted indefinite leave to remain as a Relevant Points Based System Migrant.
(c) The applicant must have, or have last been granted, leave as the Partner of the Relevant Points Based System Migrant who is being granted indefinite leave to remain.
Even if the change is deemed as "technical", I would have expected that either the relevant immigration rules be modified to reflect the change or UKBA issues (or amends) relevant IDI / guidance to highlight the change.
Hence, my suggestion that this be confirmed by UKBA directly.
