Correct. The ban is now 5 years. Whether the ban is applied or not depends on the type of misrepresentation.
Laila H - It should be easy for your to avoid misrepresentation since you haven't filed your application yet. Don't lie about anything and there won't be problems. Lie and you should expect issues that will impact the application.
Get rid of your lawyer immediately. If you hide things, you should assume you will have problems - possibly very big problems. A good lawyer would tell you to hide nothing.
