Dear All,
In my case I am in the UK and during my stay my Salary has been credited in India. Till July one department of my company was managing my Salary and after July it is being managed by global counterpart. So in my bank statements, there are two different entities crediting the Salary. To complicate the matter, after July part of my Salary is credited as INR and partly credited as USD in a bank in India.

Guidance says “An applicant should use the closing spot exchange rate on the OANDA website on the last day of the period for which he/she has claimed earnings in that currencyâ€
