As I understand the financial requirement, if the sponsor (usually the guy living in the UK) has £62,500 or over in savings, he does not need to show anything more to satisfy the requirement. His income does not need to be taken into account.
In the case where, however, his income from pension source(s) comes to £10,000 a year, this can be taken into account in meeting the requirement. Reading the December 2013 Immigration Directorate Instructions, it says that income from pensions are classed as meeting this requirement (p. 14). In the case of someone getting a pension income of let's say £10,000 per annum, then, how much does he have to also show in SAVINGS to qualify as meeting the requirement?
In addition, these Instructions are a bit confusing. According to page 14, "State (UK or foreign) or private pension" can be taken into account to meet the requirement. I will shortly receive a state pension AND I already receive a private pension.
Looking at the wording on page 14, however, I cannot add both pensions together for this purpose (ie "State (UK or foreign) OR private person"). So I can't total them up? I can only list the state or the private pension? Is this the case? Or is it just loose wording and they really mean that I can add them together as qualifying income?
