Job hunting for Columbia graduates [Job hunting]

Hello everyone: I am Lin Jinan. I graduated from Columbia University with a master's degree in environmental science and engineering in 2017. I now hold a student visa OPT, so I can legally work in the United States on a student visa for three years, but I need to extend it before 9/30. Therefore, I am urgently looking for a job related to my major. If there are any vacancies related to environmental engineering, water conservancy, renewable energy sales, etc., please contact me. I can also accept OPT that is not related to my major but can use titles related to my major to help me. May all your work be smoothly extended, such as any sales or translation work, etc. Thank you!!! Reminder: Do not rush to remit money or pay a deposit before seeing the actual product to avoid being deceived.
