I will like to know which is correct between Advice & Advise when asking for people's opinion or suggestion, because most times I have seen Nairalanders use Advice in place of Advise or vice versa but to me it dosent really matter.

So I decided to bring it to the house to confirm.

I think one is American and the other is british

The word, advice, is a noun while advise is a verb. They sound differently, however, due to their respective stress patterns.

For instance:
My uncle gave me a valuable piece of advice before travelling overseas.
He advised me to study hard for my final exams..

Same thing goes for practice (noun) and practise (verb). There are many others also. Cheers!

Advice is a noun while advise is a verb.
e.g
The doctor advised me today.( The Advise is a verb here, that is an action word, meaning that the doctor gave a recommendation to you)
I got some advice from the doctor today.( advice is just a noun, that is you as a person received the doctors recommendation)
