Hi,

As for your first question - of course, you can. Consulting companies are used to churn and no one will even think of it negatively if the resignation is done correctly. Just follow several simple rules:

• Inform the project manager you are working with at least 3 weeks in advance so that they could find a new person and do the handout. Be flexible if they ask you to stay a bit longer
• Try to stay friends with everyone (it's important since these people will be giving you the references for any future job)
• Be very supportive and do your best on your last project in order to do a smooth handout of your tasks.

As for the second question - to be honest - during the networking, most of the people will not really care about your background unless there is something unique about it. They talk to so many candidates and have so many ongoing problems that I believe no one pays any attention. However, when you send your resume it may become a bottleneck. It may become an even bigger problem during the interview when you have to explain your career choices.

All in all, I recommend to start the networking / preparation now and apply in a year or so. Best!

I would be cautious and check the visa application process as well. In the UK for example, you need to pass a Resident Labour Market Test (the employer has to demonstrate that no UK/EU applicant can fill the role i.e. you cannot pass this test for an entry-level job). You are exempt from this test if you are changing from a student to a work visa, however not if you are changing from one work visa to another. I.e. if the MBB job would also be entry-level and a RLMT exists in the country you plan to apply for, you may not be eligible to apply/can apply but wouldn't be able to get a visa.
