Operating accounts in different markets

Hi,

If someone has LLC in USA and is selling on two different markets like Middle East market and USA market. Does it impact other marketplaces in case there is a suspension?

Secondly, if we are selling in Middle East market with LLC details, then what about taxation?

Is the taxation applied for the selling country and the LLC based company both OR Taxation is applied only on selling country?

If someone sells on multiple marketplaces under same company then the accounts will be linked and depending on the issue both accounts can be suspended if one gets suspended for whatever violation however nothing wrong to sell on multiple marketplaces.

Regarding taxation you need to check on internet if there is any double taxation treaty between USA and UAE.
