N400 Questions - Entry and exit time out of US on N400 and quesiton on affiliation.

[tafn430]

For the question that asks when you left and then re-entered the US, how important is it to be exact. I took a vacation to Canada 3 years ago, and being a green card holder there was no need for a passport and hence no entry/exit stamp. I can say with certainty when I left the US , but am not perfectly sure (+ / - 3 days) when I returned. How important is it know the exact date. Any advisie?

Another question is about ever being a member of an organization, society , club etc. Should we include professional organizations such as IEEE etc???

Thanks.

1. Try as much exact as possible. All they are trying to figure out is whether you have been staying in US more than anywhere else or not.

2. Yes.

Do we need to include social associations such as Inida association, Temple association, Telugu association etc?
Thanks

You don't have to. However, there is no harm if you do.
