Is it possible to hide my US credit history ?
I am a US resident but a citizen of another country.
Can I conceal US credit history by not disclosing I had
anything to do with the US?
You might not want to ask questions like this on the internet, you might want to check with a lawyer about your particular situation. Who are you trying "not to disclose" your US credit history to? In general you need to give someone permission to access your US credit file. Some Canadian mortgage lenders, if they know you used to live in the US, will ask your permission to check your US file. You don't have to give it to them if you think it will hurt you, but then they may not give you credit. US and Canadian credit bureaus, credit providers, etc. are regulated by different laws. Information from one report should not show up in another.
