Let's simplify this.
If an applicant gets married after the application was submitted, he/she cannot be refused due to a change in circumstances unless that change makes him/her ineligible for the particular program (CEC, FSW, FST) he/she applied under. So getting married or adopting a child after AOR does not affect your CRS, however, it does affect your eligibility for the program, and when reassessing your application, if an officer determines you no longer meet the program requirements, your application could be refused.
Really sorry to hear this and forgive me, but I have a strong hunch you might be missing or misinterpreting some crucial details from your refusal letter. Could you please paste the entire refusal text in this thread so we can provide you with the most instructive advice on how to proceed.
I have now completed the assessment of your application for a permanent resident visa as a member of the Federal Skilled Trades program and I have determined that you do not meet the requirements for immigration to Canada.
Subsection 16(1) of the Immigration and Refugee Protection Act states that a person who makes an application must answer truthfully all questions put to them for the purpose of the examination and must produce a visa and all relevant evidence and documents that the officer reasonably requires.
You were asked on January 19, 2016 and May 12, 2016 to provide a completed and signed Schedule A for your Spouse the following evidence and documents within 7 days respectively in order to assess your admissibility to Canada.
These letters informed you that if this office did not receive the required evidence and documents from you within 7 days of the date of the letters, your application would be assessed on the basis of the information that was already before the officer. You were warned that failure to provide the additional information could result in the refusal of your application.
To this date, we have received a Schedule A which is incomplete for your Spouse.
Subsection 11(1) of the Act provides that a foreign national must, before entering Canada, apply to an officer for a visa or any other document required by the regulations. The visa or document shall be issued if, following an examination, the officer is satisfied that the foreign national is not inadmissible and meets the requirements of this Act.
Based on the information that is available, I am not satisfied that you are not inadmissible and that you meet the requirements of the Act. I am therefore refusing your application. Following an examination of your application, I am not satisfied that you meet the requirements of the Act and the regulations for the reasons explained above. I am therefore refusing your application.
Thank you for the interest you have shown in Canada.
Review of eligibility is passed, means they added my spouse. in refusal letter they only pointed Schedule A form.
