This is partially copied and pasted from one of my previous answers. I think the two I’m going to mention below will provide you with the necessities; travel will probably be yours to cover, however. So at least, you don’t have to worry about some of it. Or are you looking for travel expenses and other expenses to be paid for?
I’ve looked into missionary organizations too. One I heard of from going to a fair and another I found by searching online.
Jesuit Volunteer Corps
(jesuitvolunteers.org/ – I think this is the US site but I’m not sure)
(jesuitvolunteers.ca/our-leadership – This one is for the Canadians)
Dominican Volunteers International
I believe you can choose where you want to go and they will, of course, also suggest for you something that suits your abilities. I’ve explored this one a bit more. They have a list from 2012 which will hopefully give you an idea of the areas (geographical and missionary-wise) that they do work in. Go to this link:
Then press “The communities that have requested volunteers” (in bold, blue text) and download the PDF. Just to let you know, once you click it, you might read the first place and think “It’s in Spanish, I don’t understand” and leave it at that. But look through each one; some are in English, French, etc (it’s not a lot to look through, really).
There are also testimonies, pictures, etc. Their Facebook page also has some pictures.
For the Dominican Volunteers international, in one of the pages (dviop.org/eng/index.php?option=com_content&view=article&id=19:receiving-communties&Itemid=32), it says:
“The Dominican communities who wish to receive volunteers need to complete a form (available in four languages) with information about the project, the characteristics of the community, the expenses that they will cover. The receiving communities should respect these expressed commitments.”
So I think this one might be negotiable since it is up to the receiving community as to what they contribute in terms of expense coverage, but keep in mind that the Dominicans are a religious order who are under the vow of poverty and we wouldn’t want to financially burden them.
I hope this helps! I’m curious what you think and would like to hear your thoughts on this so if you have the time to give feedback, please let me know. God bless!
