Hi Safiullah, 

I'm sorry to hear about your situation. 
This comment system leads to the team responsible for transparency and accountability work in the public service. We host datasets and records about many things, including historic statistics on immigration and visa applications, but we do not deal with these services directly. 
I would recommend you contact UNHCR Canada: http://www.unhcr.ca/contact-us/  
You can go to the following website to learn more about immigration: 
Immigration, Refugees, and Citizenship Canada: http://www.cic.gc.ca/english/immigrate/apply.asp 
You can email your local IRCC office for direct help: https://www.canada.ca/en/immigration-refugees-citizenship/corporate/contact-ircc/offices/international-visa-offices.html 
I hope this helps. 
Warmest Regards,

The Open Government team

We have a section or so of land near Acme, Ab. It Will soon have additional water resources from a new nearby dam. Is it worthwhile updating to an irregation system?

Clean API. Good documentation. My only feedback is to check the Intermediate SSL certificates on the API's server? I was having trouble with the SSL handshake using python requests library (disabling SSL verification works, but is clearly not a good solution). I'm not an expert in certs but it seems like its missing a root CA cert.

Every set of data I try to access through the app is completely empty. What format are the data in? The instructions are vague
