Various travel restrictions will be outlined in the contract between the gestational surrogate and the intended parents.
Due to varying laws and available medical care, international travel is generally restricted beginning at contract signing.
Limitations on domestic travel generally start between weeks 24-32 of the pregnancy. There may be several restrictions, beginning at different points. For example, travel to any state where surrogacy is restricted may being at 24 weeks, and travel outside your state or beyond a certain range from your hospital (usually 50-100 miles) may begin at 28 weeks gestation for a multiples pregnancy and 32 weeks for a singleton pregnancy. At this point in the pregnancy, it is important to be near the hospital where you plan on delivering, because all of the legal paperwork is completed with that hospital in mind.
