1. There is nothing wrong in bringing fotos or idols of
Hindu Gods. But dont "flaunt" on it to exhibit all
that "I am Hindu devotee". Be a moderate. Keep a low
profile and perform your rituals at closed home. Again
I repeat the words - DONT FLAUNT, NO EXHIBTION

by the way, why fotos and idols in plurals... bring
one foto and one idol. You want God,,,or Gods ?

2. There was a Hindu temple and Govt kept a blind eye to
allow a little bit of freedom for other religions. But
people "misused" the freedom to start "exhibitionism"
At last Govt started action, some of them sent back to
India. !!!!

3. I dont think you have a place to do yearly rituals for
your dead relations. Either you have to go home at
that time, or you schedule the same at the time of
your vacation.

By the way, you come here to "work and earn" right ?
not to open a "branch office" for any Indian temple.
Better you decide what your priorities - to perform
rituals, then be in India. to earn money, then forget
rituals for some years
