I completed my BSc degree in biology in 2017 and then joined masters in microbiology after one year and completed it just recently this year. However a bsc and msc degree in india dont really equip one with practical skills to get into biological companies. I thus thought of applying to a PG diploma in biotechnology or environmental technology to study further and then work. But I recently checked deeper into student visa rejection in such cases and I am unsure if it's a good decision to go ahead with it. Are chances of getting my student visa rejected high?
