Can I create a DBA in a state diferent that my company is registered?
Unfortunately it is not possible to open a DBA other than in your company's state of formation. The only way you would be able open a DBA in a different state would be if your company filed a foreign entity into the state you wish to operate your DBA from it's state of origin.
Once your company is filed as a foreign entity into a different state, in addition to your company being able to operate business anywhere in that state, you would also be able to register your DBA under your entity.
I hope this answer was of some help.
