Financial hardship EAD is not something new. its available for all F1 students (regardless of country ), you only have to convince your DOS. Seems now DOS's will be forced to provide EAD to Nepali F1 students without any coaxing. what this basically means for nepali F1 students without TPS is now you are allowed to work outside the campus legally (with your new EAD they will provide) as long as you maintain required course load for fulltime students. thats the only difference.
TPS with EAD on the other hand has its own benefits and drawbacks. on benefit side, if you drop out of college tomorrow, and your sevis is terminated, you will still be in legal status and can still change to other visa statuses or green card sponsors though job or marry to GC later on. when you leave the country you wont be automatically barred unlike if you terminated your sevis without TPS. on the drawback side, while on TPS, if you want to travel outside the country you have to apply for AP.
So best option is apply for TPS with EAD, maintain F1 status (while traveling with AP, if you have valid status, its easy at POE) and work outside campus with TPS EAD if you need to.
