Dual intent is the legal concept of having intent to enter the US in order to live permanently and having the intent to live in the US for the duration of the visa. This was discussed above in the section called Non-Immigrant vs. Immigrant Visas above. For O-1 purposes the alien may only have the intent to remain for the duration of their visa and must show that they have some home ties. However, the showing of home ties does not need to extend to the alien keeping a home residence. This is because the O-1 visa can be granted initially for three years and forcing a person to maintain two residencies for such a long time has been deemed too burdensome.
