Yes, receiving an LOR from an NGO is totally not an issue. This could possibly provide a very pleasant impression to your profile. It all relies on how well is your LOR written. In general, the rules for an LOR are: ? Choose someone with whom you have worked closely for at least six months, preferably one year. ? The work experience should have been recent, within the last three years. ? This person must have been in a supervisory position over you-they do not have to be your boss formally, but they must have evaluated your work product directly. If you have nice tales about making a powerful commitment and having an effect on your job with the NGO, that might be an optimal option for an LOR.
