There is a warrant on my name in Texas. I live in Washington DC and I am planning to get married. Can this warrant hinder me from fulfilling my wedding plans?

It is all a matter of the gravity of your crime for which the warrant was issued. If it is homicide, you will probably get married behind bars. If it is only class C misdemeanor, Texas’ authorities won’t bother to spend their time on it. You should consult a lawyer and inform him/her with the specific details.
