I empathize with the challenges, but being here is a blessing and he's wasting it, someone needs to take the initiative to learn English.
If the government doesn't have  enough spots for official language courses ,ask your Mosque to start a community program. If they won't help, swallow your pride and ask your daughter to get you some "learn english audio tapes" from a local library and ask for her to help. 17months without the ability to communicate for someone that was a Mayor anywhere says more about him then anything. Swallow your pride dig deep and be the change you need to move forward. Happiness will follow
