Hi,
I'm not familiar with exploratory visits for BC immigration. Hopefully someone else can advise you on this aspect.
Do go through the CIC website, this forum, Google..... maybe you'll find more information.
Can I go for 1month visit.
From a TRV perspective, a one month visit indicates weak ties to the home country. That's why do keep your visit to 2 weeks max.
I am very genuine. how can I get them assured.
Genuine purpose of visit + finances for your trip + proving your strong ties to your home country
But I have an email from business broker stating - Mr. Singh I hVe some best investment options for u. U are Invited to our office for business.
IMO this will not work for your TRV.
If you apply for a business TRV then you
must include an invitation letter from a potential business partner in Canada + 24 hour contact details of that person.
My advice is to also include a day-by-day business itinerary.... of what you'll do/whom you'll meet/prove why you need a visit of 2-3 weeks.... in addition to other business documents.
Should I apply for multiple or single.
All TRV applications are automatically considered for multiple-entry. It's up to the visa officer to issue an MEV/SEV
Cheers
