May I accept reimbursement for interview travel expenses from a company?

[asd_dsa]

I recently bought the air plane ticket to attend an interview. The company says they will give me a check for it.

I am in F1 visa status. Can I accept this money from the company, as I remember that I am not authorized to accept money for any work until I am authorized for employment?

Is this a normal thing? Accepting a check for reimbursement for travel expenses while on f1 visa?
Will this affect me in anyway when I am applying for greencard/H1B?

Thanks for your help,
