Yes. It is not necessary to incorporate the firm in Texas. However, the firm must be registered with the Texas Secretary of State’s Office to conduct business in Texas.

It depends.
If the firm will handle matters involving Texas law, the firm must have an attorney licensed in Texas practicing in the Texas office. The Texas lawyer may practice law as an associate or other nonpartner lawyer if that attorney “(1) qualifies as a ‘firm lawyer’ reasonably considered to be ‘in’ the law firm under the factors discussed in Opinion 577; and (2) is given the responsibility and authority to make decisions about the firm’s practice of law in Texas.” The firm must also designate a resident agent for service of process. See ethics opinion 686 (January 2020).
If the firm will not handle matters involving Texas law, the firm does not need to have an attorney licensed to practice in Texas in its Texas office. For example, a firm that solely practices immigration law and opens an office in Texas can hire an attorney who is not licensed in Texas if that lawyer does not handle any immigration matters that involve Texas law, such as matters involving special juvenile immigrant status. See ethics opinion 516 (July 1996). Another example is a lawyer licensed to practice law in another country or state who practices remotely in Texas but solely handles matters involving the law of the country or state in which the attorney is licensed.

If the firm will practice Texas law in the Texas office, the firm should plan to work through any ethical issues that may arise and resolve any differences between disciplinary rules of the state in which the firm is currently operating and the Texas disciplinary rules, including advertising rules, nonlawyer ownership of the law firm, conflicts of interest, fee splitting, and the like.
