Does an online business need Foreign Entity registration in all 50 states?

[TheDapperLove]

I understand entity creation and most of what envelopes that. To any drop shipper or Shopify that can point us in the right direction would be appreciated. I do have a meeting set up with a lawyer to make sure we are legally secure. My question would be this if anyone has actually done this:

- LLC formation will be in Delaware/Nevada, I physically live in another state. Did anyone have to register a Foreign Entity in all 50 states even if the business is online? Does anyone have experience with this?
