How about honesty andcommitment at teaching, is it the main element to have?

The role that international organizations can play depends on the interests of their member States. States establish and develop international organizations to achieve objectives that they cannot achieve on their own. By the same token, States will not permit international organizations to do things that constitute, in the eyes of these States, interference in their internal affairs. This is particularly true in the very sensitive field of international migration. The entry, economic activities, residence rights, etc., of foreigners are viewed, to this day, as falling under the sovereignty and reserved domain of States. In the field of international migration, no State likes to be told what it can or cannot do - neither by another State nor by an international organization

yes of course,the honesty has abig necessity in teaching
