Why does USCIS take such a long time to process an application for employment authorization (form i-765)?
Asking a "why" question about the government will likely never get you the answer you want.As a special request, I will humbly speculate as to the reason why a government agency takes X period of time to do Y.As a general answer, which can probably be applied to any government agency, the agency has a finite number of resources (only so many dedicated staff members) who must therefore (thoroughly) review and approve/deny/request more evidence with regards to each application/petition received.The three months it takes for USCIS to process an EAD application for F1 students on STEM/OPT is actually on par with all other EAD application types. In fact, USCIS, for the past few years, has been fairly consistent and reliable w/ the processing times for EADs in general.USCIS employs a dedicated team of officers to review certain types of applications/petitions. I can only speculate that because each officer has a massive number of applications/petitions to review, it takes approximately three months for the life cycle of an F-1 student's EAD application to be complete, assuming all the required documentation has been submitted.IMHO, three months is remarkably fast.
How much time does i-765 takes to get approved?
I’m not sure what type of I-765 you filed (L-2 dependent? H-4 dependent?) and with which service center. You can find the processing times for the Vermont Service Center here: https://egov.uscis.gov/cris/proc... and the California Service Center here: https://egov.uscis.gov/cris/proc...*I am not an attorney. Please do not misconstrue the above as legal advice.*
