Could someone care to share their experiences and shed some light on this matter please?

advantage:
sooner or later, you will get job
they will sponsor your H1 /opt extension


disadvantage:
would be really hard to handle interview since you will have resume wth 5-6 years of experience
you will get your ass whooped in your first project  or in worst case, you will get fired
will be stuck on some kind of legal binding ( this will not be a big deal)

Kaam paisakeko manche lai nikalne chance kattiko huncha? 

 ya! about getting a job -- they make things lot easier..
but i cant understand the legal obligation to be attached to them in the future provided that you dont get fired during the first project..
also, there are way too many of them! how to know who can get you the best job?

hope someone knows...

 You guyz are just not smart enough to get a job through consultancies.

Nepali ma sodha na yesta kura haru ta. Aaajkal dherai halla vai sakyo ki resume nakkali huncha vanera. Tei vayera interview pani dherai tough huna thalekocha. Yesto kura haru lai english ma lekhera internet ma post nagarau na sathi ho. Google ma 1 search hane pachi ta sabai le dekhi hale ni. yesto kura ma ali bichar puryau sathi ho.. yesai ma hami sabai ko kalyan cha.

ma ta dherai jaso faida nai dekhchu.. Yedi timi lai halka knowledge cha ra ali kati mehnat garna sakchau vane, after second project.. you are all set. H1 vaye pachi timi afai around $80k ko job khojna sakchau. But 1st & second are very tough and you need to have capability and confidence to fight through it. Maile computer OS ramro sanga install garna naaune manche pani successfully tikeko dekheko chu.
