this is the last email i sent

I still need 2 more classes to graduate at winter quarter (Jan-Mar) but I
plan to take them at nights or weekend. Right now I am looking for a
full-time position. The reason is I do not want to wait until I fully
graduated because that may waste some time. I am eligible to work for full
time.

Thank you for your Concern!

Best Regards,
any mistake or they just concern my working hours.
they asked me only do i have gc and did i graduate or not.certainly, i said i have gc. and i said above about my graduation.
