How registration works with Texas
Procedure1
Procedure 1: Is Texas registration required?
Definition: a foreign LLC is one formed in a different state. It registers before it does business there. Without registration: Its own lawsuits wait in Texas until registration (BOC 9.051(b)). Contracts already signed stay effective (BOC 9.051(c)).
Every LLC must name a registered agent with an in-state street address. The address has to be a street address where papers can be handed to the agent during normal business hours. A mailbox service or answering service alone does not qualify.
After registration, a foreign LLC files the Public Information Report, May 15.

The state's fees were read from official pages, which are listed below. Over three years they come to the filing, two reports and, in some states, a minimum tax.
The reasoning behind the ranking
The deciding criterion was procedures the price performs, worth 28% of the reading.
Because the LLC came from another state and now works in this one, a single provider spanning both measured best.
