If you have the single entry visa issued after the pandemic then you’re fine. Disregard that. You will get the green code if you follow the testing and submission instructions.
If you are traveling on a residence permit, it is a black box of mystery as to whether or not the consulate will give you the green code even if you do follow the instructions. The success rate varies from consulate. For DC (responsible for the Dallas AA flight), the success rate seems to be 0%. For LAX it seems very high. SFO seemed more challenging as myself and many other coworkers have been rejected there.
