Hi there, if this is the wrong sub forum for this question please let me know and I will repost.

I am on an F-1 and received my EAD card. The latest date for me to start working is May 17 2016.

I received a job offer and was to start on April 11, however, they called me today and told me that my urine sample for my drug test was too dilute, and I have to go give another sample. The problem is that by the time they process a new urine sample, I will have missed this months orientation/start date of April 11, and will have to start on May 11.

I am worried that they may rescind the offer/hire someone else in the meantime? I am probably just being really paranoid, but in order to be safe I was thinking of applying for a volunteer position, so that at least i have something to meet the minimum by May 17 2016.

Questions:

Should I just send in my offer of employment for this job to USCIS now?

Should I wait, and then send in an offer for volunteer work, and then send in the offer of employment after I am sure that I will be working?

Can I both volunteer and work? or only one or the other?

Your help is greatly appreciated!!

Thank you!

Is this EAD through OPT? Would the job and the volunteer position be considered directly related to your major? Are you concerned about the drug test?

good luck

No I'm not concerned about the drug test, I just drank too much water the day of.
