In reviewing your application fully, I really think your original health program in Africa is the best fit for you. You are always free to participate in whatever secondary activities interest you (ie, English tutoring, community development, etc.) as long as the community has expressed a need in that area.
I plan to issue your invitation this morning and I trust that it will find you at your address later this week.
MY INVITATION IS IN THE MAIL!!!!
Based on the fact that it's for my original SSA health nomination, I am about 99% sure my invitation is for Uganda.
