I know only 5 who quit in the last 3 months. However, I know a lot have applied with other airlines and many still have seniority numbers and recall rights with American and United. Most will have to make a decision between 2016 and 2019. As it stands now most say the will leave Cathay, but that can change.
Actually the company got work visa's for Canadian captains and fo's based in the US. They just did not renew the visas for the fo's. Funny though all the Americans based in Canada do not need a visa. You would think immigration rules would be similar between Canada and the USA.
