I live six months of the year in Brazil and work the other six months in Canada. I married a Brazilian woman in 2011 and obtained my permanent visa (RNE) in 2015. My permanent visa is valid until 2023. But I divorced my Brazilian wife in 2016 due to irreconcilable differences. Now she is bitter that I have a new Brazilian girlfriend and claims that the Federal Police called her about our past marriage and my RNE. I suspect that she is lying and called the Federal Police in an attempt to revoke my permanent visa. Can she revoke my permanent visa?
