I won't be claiming for 50 points but my employers don't want to continue after completing 2 years can I change the job after applying I am dead end
Very hard to understand what you wrote. Let me ask, do you mean:
1. You said you've already received an ITA. You claimed 50 points for job offer and don't have an offer of employment or LMIA?
2. Are you going to finish two years of exp in June, but IRCC ended up giving you points for 2 years regardless?
Or is it #1 and #2, both?
