I’m going to apply on paper .
They must include a color scan of their US visas in the TRV cover letters + submit the passports that have this US visas + request VFS staff to mark their passports for CAN+ processing.
Yes me my wife and one of my kid when she turned one 6 year back we all went together to celebrate her first birthday in New York so basically my kids visa is expired last year
This child cannot apply under the CAN+ program.
but my wife is been on tourist visa for Britain 9 years back .
Although it is travel to a visa-required country, it does not help much because it was several years ago. Hopefully, she had visited the UK for just a couple of weeks. She can include a copy of this visa.
That’s the travel history and one of my kid is going to turn 3 year coming February so his passport is fresh
You will need to work very hard to prove that each applicant has no intention to overstay the visit i.e. they have strong ties to return to India.
IMO, you would want to visit another visa-required country instead of applying for TRVs at this point in time. Here's why:
1. Your children are very young and don't have any ties to India which is understandable.
2. Your entire family has not traveled abroad to visa-required countries (US, UK, Schengen, Australia, NZ, etc).
3. Your wife is a stay-at-home mom and does not have any strong ties to India
4. Not sure about the purpose of your visit
5. You were probably granted a TRV because you had indicated your wife and children as family ties to return to + your valid US B1/B2 visa
In short:
I believe given their present circumstances, your family members have slim to none chances of TRV approvals. You can certainly try though
