Per recent events and experiences, the Visa Office would like to advise that our current government administration appears to be applying more stringent background checks and stricter regulation interpretation. Also, due to peak travel season there are longer wait times for consular visa interview appointments, and longer visa processing times.
Keeping these factors in mind, the Visa Office advises that anyone inviting an international visitor to the lab should plan ahead and complete all internal processes as soon as possible. Please plan on allowing for a minimum of three months between invitation and expected arrival of the international visitors. Visits beginning less than three month in the future will have a significant risk of later arrival or trip cancellation.
