I am a Lamar Graduate. Good thing about Lamar is you get In-state, that means about $2000.00 for 9 credit, i.e $8000.00 to graduate. But electrical engineering is not that good there (only communication, no power). Graduate keta haru either get job in their feild (20%) or goto consultancy (80%). But again, you can complete masters in 1 year time. If he has friend there, Nepal ma huda nai kam fix huna sakni prabal sambhawana cha.

UTA is good, but without scholorship it sucks.

No idea about miniasota.

What is ur brother looking for. Good university, or easy way to survive till he graduates?  If it is second one, Lamar is the best choice. Graduate pachi Job pauna jun university ma pade pani it does not matter that much but lamar sucks in this matter a bit more than other universites.
