Don't trust this company especially if you are on OPT/CPT
Pros
On time pay is the only Pro But please remember there are other main factors which you need to consider like visa filings etc in which Collabera sucks
Cons
They give lot of fake promises before joining the company that they will file your H1b or take care of extensions and everything. But when the time comes they will tell many reasons which doesn't make sense and won't file your H1b. If you are on OPT/CPT please don't consider this company at all. I have struggled a lot with this company a lot and wasted my last year of OPT and one year of CPT as well. This is my humble request to all of my fellow master students please don't consider this company at all and don't face problems like me. They will just utilize your EAD time period and let you go away once it is done without filing H1b.
