Is it possible for foreigners to work as English teachers in Namyangju/Guri?

Hello! It's been a year since I came to Korea, and I am currently looking for an opportunity to work as an English teacher in Namyangju/Guri. As a foreigner, it's not easy to find a job here. Especially since I need an F-visa, I am also worried about visa issues. Does anyone have a similar experience? I would really appreciate any tips or advice on how foreigners can work in this area! I have tried using the Zigbang app and inquired at a few academies, but they all said it's difficult because of the foreigner visa... I would be really grateful for any help ㅠㅠ Can you share any information on good academies or job openings?
