what is the best way to apply i have an USA citizen wife but i was deported from USA for Felony assault after i use to has a USA green card thank uuu all of u
You can apply through an economic immigration stream just like anyone else. However the process will most likely be longer due to the felony - you'll almost certainly have to apply for rehabilitation before you can apply to immigrate. Depending on how recent the felony was, it's also possible you may have to wait a few years before you will qualify for rehabilitation and can apply to immigrate to Canada.
How recent was the felony? When did you complete any sentence or penalty related to the felony?
The fact you have a US citizen wife or used to hold a green card has no impact on the process (either positive or negative).
