my husband didnt know that his mother erased my name. he just known this time when he recieved the letter from IRCC that his ineligible to sponsor us because he did not declare us. i feel so terrible to. and im planning to get an skilled education to get in canada. but if i do that can i go with my children together or i should sponsored them after i get my pr?
As canuck87 has said, it would appear your mother in law removed you from the application because, without doing that, her son wouldn’t be eligible for sponsorship by her.
Whether or not she knew what the consequences would be is irrelevant now, as you’ve had your official confirmation from IRCC that you and your youngest child can never be sponsored by your husband. Your mother in law and husband could be investigated for immigration fraud/misrepresentation now too, as they lied on an immigration application. It’s up to IRCC to decide if they take any action against them.
As for you moving to Canada on your own, if you fit the criteria and apply for PR via an economic stream, then you should be able to sponsor your youngest child to come with you. Moving to Canada on your own as a PR, then sponsoring your child would mean being separated for a year or more during the process. I wouldn’t want to be away from my child for a week, let alone over a year.
Before you do anything further, take the time to understand what’s going on, the importance of telling the truth, and get your affairs in order. You will have to declare your husband on any application for PR that you make. That could trigger an investigation of his move to Canada without you, as the dates aren’t going to sync up and IRCC could see that you were both married before he moved to Canada as single, unmarried dependent of his mother.
IRCC will also have on record that you and your youngest child were deemed illegible for sponsorship by him too. I would expect a lot of investigating of any future and past applications from you and your family now. Be prepared for that. My advice, for what it’s worth, would be to get a lawyer to assist you. You’re facing a large potential uphill battle to make any of this work. Any potential application you make is on the basis that your husband isn’t found inadmissible due to the misrepresentation of his own application. If that does happen, he will likely be deported back your home country anyway. The upside is that you’ll be together again, the downside is that you won’t be in Canada.
All of this is worst case scenario stuff, but it does happen to people. Misrepresentation is a very serious issue for IRCC. In your husband’s case, it’s not like it’s a couple of years of overstay he didn’t declare, and that IRCC can simply forgive it and move on. He and his mother committed probably the most serious immigration violation you could, without actually committing a criminal act.
