Hi. I was married to my husband for 5 years. This Saturday, we will have been separated for 12 months ( separation). He cheated on me and he and his girlfriend told me that he married me only to get Australian citizenship. He was granted citizenship approximately 2 years ago. I reported it to Immigration as soon as I found out, about a year ago. Will he face any kind of punishment for this? Can his Australian citizenship be revoked or is it too late? There should be some kind of immigration law that punishes people who do this.
