I will expect at least a 15% increment, with a lean towards 20%. Banks bonuses especially for the functions situated off-site like CBP, are pretty mediocre to put it nicely. Your increment has to make up for this.

Also, the travel will be intense. Even with shuttle buses, the travelling time to and fro everyday will be close to 2 hrs. Not to mention the times when you miss the shuttle bus due to working late, etc. Something for you to consider if you put a value on time outside of work on weekdays.
