Taxes as a new immigrant to the country after 2 years.

[JustMarried81]

I been in the country for a few years. I use to sell things online when back home and it was going into my paypal account and then my countries bank account back home. I been doing it for a time frame of 5 years and still on going. Do I claim this on taxes here even tho it's all back home? I would open up a new account online but the sales would start from 0 and it's beyond slow it's why I keep it going like I have for the last few years it's mostly online like ebay/amazon. And their system for newer accounts don't give out sales and I been doing it for countless of years already.

How does this work?
