I think the Job market in the field of Biostatistics is pretty good right now compared to other fields. But to work as a Biostatistician, you'll need some hands on experience in the industry. However you can start as a Biostatistician I and get some experience then eventually that will lead you to a good position..You can also work as a SAS Programmer, Statistical Analyst/Programmer etc..Prepare your resume now and apply for jobs around March if you're graduating in May.

@Kanchha-dai----I think everybody does what you said but that's just the saying, it doesn't work out all the time. People need more inputs from the people in the same field or who went through same process..
You always see people in sajha asking about F1, H1, how/where/when to apply OPT and other similar questions like that, right ? But why ? They can ask their advisor ? But they want answers from the individuals who have done the process so that it sounds encouraging and easier.

Just my 2 cents.
