Tier 2 Change of Employment

[scro2014]

HI,

just after some advice

I have been and am currently on tier 2 general for past few years (not more than 3), I've been accepted for a job with a new employer, they have completed RLMT with job centre plus and other places for at least 28 days,

they have just been registered as sponsor with ukba

I intend on applying for new tier 2 visa (in country) as soon as i get the COS number.

I was planning on doing the premium post as the standard service seems to take 8 weeks and i want to start by end of april,

is there anything I have missed?

my salary goes up and my hours stay same, I can't think of any reason why it would be rejected?
