What can I do to ask forgiveness from Allah, if I remove the hijab?

I started wearing my hijab since 2016, no one forced me with it and it was my choice, and it has been a year for wearing it, but the problem is the job of the family that I am working in. It mainly deals with men and our customers are for men. If I plan to study a major for this job, I have to remove my hijab, especially in my country that I live in. It is one of the reasons for a Muslim lady to be forced to remove her hijab, unless if she is married or the guy who would want to be halal for her, ask her to wear hijab. If I wanted to study a major and it is not eligible for a lady to be wearing hijab for this major or job, would Allah punish me for removing the hijab? I have chosen it with love, because I wanted Allah to be near always and for so many reasons. What can I do to ask forgiveness from Allah, if I remove the hijab? Can I fast for one week asking forgiveness? I know Allah is kind and knows what is inside my heart, and Allah knows that even if life forced me to remove the hijab, I would still come back to wearing it, but I would like to know, if I remove my hijab, what can I do so that Allah would forgive me?
