I need to apply for visitor visa for my in-laws. My questions is what additional documents are needed to prove that they are my in-laws ? Like my wife's passport(having her parent names) or my wife's BC. If wife's BC is not available then what ? Is BC a necessity ? Anything else ? also, one more question about bank statements ? I have recently done too many transactions with my money in the bank, like investing in CDs, govt bonds etc. So, during the last few months, my bank balances have been really going haywire e.g on day it is 15000, next day it is 500, then after some days, again I transferred some money (like $20000) into it and after some days, took all of it out electronically. So, is it advisable to send such bank statements with so many frequent ups and downs ? Would it have any -ve effect ? Or shall I just send a bank letter stating date account opened and current balance and copies of paystubs and employment letter? Please advise !!
