• The Tier 1 (General) route will remain open in order to enable those with existing leave to enter or remain under Tier 1 (General), or its pre-PBS predecessor categories to extend their leave. The points threshold for extensions will, however, be raised to 100 for those who were required to score 100 points when they were originally granted Tier 1 (General) leave. The points requirements will otherwise be unchanged.
• Those not already in Tier 1 (General) or a prePBS predecessor category will not be able to switch into it after 6 April 2011. This includes those with existing leave to enter or remain in the Tier 1 (Post Study Work) category or its predecessor categories, and those in Tier 4. They will not be able to switch into Tier 1 (General), but will be permitted to switch into Tier 2 (General). The allocation of a CoS for the purpose of such a switching application will not count towards the annual limit in 2011/12 nor will it be subject to the RLMT where the worker is switching from a Post-Study Work category and has been in post for six months or more.
My two cents:
Until such time that the government issues a statement of change in the parliament or announces the exact details of changes in the immigration rules and issues a revised policy guidance, any statement made in the said document is subject to individual interpretation!
So, in my humble opinion, being a bit more patient and waiting until such details are made public may be a wise thing to do. Details of any changes to be implemented from 06-Apr will have to made public beforehand, so not long to wait for ... and everything will be crystal clear then.
