I'm in UK on short term ICT landed here 1 month back, and I would like to sponsor for my mother in India.
1. Can I apply general visitor visa or family visitor visa to UK?
2. I have all the documents you have listed in blocg except the follwoing.
6) Sponsor's High commission certified letter (e.g. Indian High commission in UK)

3. Reason for visiting UK: Tourist purpose and meet my son, is it ok?
4. Reasons for returning to home country: My mother aged 68 years do not have property in India in her name and do not have enough bank balance? What evidence I can give? Can I say my mother does not have bank account (of course she has one but only 20k balance?)
5. Can I get some funds (2lakhs) from my relative as gift and take a statement and produce the same for Visa?
5. I have covering letter from my company in India is that enough?
6. My mother not working but she has income of around 20k per month rent from my property, can I show this?
7. She does not have PAN card and IT returns? is it manadatory? If yes then I will wait for some time to get this done.
8. Sponsor Bank Statement: I'm applying for visa next week I mean 8th Jul , do I need to provide Jun months bank statement? Jun month statement from my bank is not initiated so can I take a online statement and produce the same?
9. My May month's bank balance in India was 85k is it sufficient? Do I get some funds as gift from my friend and take a statement till date?
10. Can I apply visa in fast track and get it in 3 days?
11. In case visa gets rejected, can I reapply?
