visit visa for my parents

[saqibs]

Hi,

I am preparing visit visa application (for 2 years) for my parents. I require your precious advises for preparation.

Thanks in advance!

My parents visited us in Jan 2014 (on a 6 month Visa) when my son was born and they stayed for nearly 4 months however we mentioned only for 4-5 weeks in application.

Do i need to provide evidence/details why they stayed for more time than mentioned in application form? If yes, what could be the better details?

Parents doc details:
My dad is a retired govt officier, I am including following documents:
-Dad's pension documents
-Bank Statements
-Property document
-My Brother's document (salary slip, bank statement) who also support my parents.


Sponser details:
I am self-employeed (an IT contractor), providing
my salary slips, personel bank statements, Company registration document, , company invoices, company bank statement (to show that dividend are coming into my account as there is no slip for dividends), recent tax return along with receipt.

Kindly advise if I am missing something or I shouldn't include.

Regards,

Thanks,
