Hard to say if this matters. It's a Tunisia specific issue. A similar situation in the Philippines used to be no problem, unless you wanted a new passport in the married name. Now, a marriage outside the Philippines must be registered through the Philippine Consulate abroad, or there is a definite problem. Unless there is a similar current issue for Tunisia, no worries. Maybe ask in the appropriate regional forum, or the situation may be mentioned in on the US Embassy for Tunisia, website.
