Re: Visit Visa Application for Parent with Rejected UK Visa Application
Think from the visa officer point of view - he wants to "check and make sure" that refusal of UK visa was not due to some very serious reason. For example, working in underground nuclear silo in Iran or whatever will probably be suspicious.
And all of those visa officers really love paperwork and documents. More documents and papers you produce, the better. With the explanation make sure to explain that it was due to (for example) missing documents X and Y, and meanwhile they have obtained them (and attach copies)..
