Upon his return to Milan, Falck was appointed Schultheiss bailiff (vice-governor). To thank him for obtaining the elevation of their church, the authorities of Fribourg granted him the right to build a chapel in the new collegiate church for himself and his heirs. As soon as the construction began, Falck announced his intention to go on a pilgrimage to the Holy Land. On 20 April 1515, after obtaining a safe-conduct from the doge Loredan, he left for Venice, where he boarded a galley to Jaffa. On his return from his pilgrimage in January 1516, Falck found that the political situation of his homeland had considerably changed after the defeat of Marignano. Despite his role as head of the pontifical party of Fribourg, the city renewed its trust in him by naming him Schultheiss bailiff (vice-governor) and entrusting him to negotiate peace with the King of France. These new responsibilities raised yet another controversy: Falck was asked to prove his innocence against the "false rumors" that circulated about him. Having played an important role in the negotiations of the "perpetual peace" (1516), he went to Paris with Captain Hans Schwarzmurer to obtain Francis I’s sealing of the treaty. The Confederates also put him in charge of negotiating a scholarship program for Swiss students wishing to study in the French capital. Falck obtained the funding for Swiss students: each canton could send one student for a stay in Paris. The King also made him a "golden knight" (eques auratus) to ensure his loyalty.
