How can my permanent force field let in guest while maintaining internal pressure?

I am facing a great difficulty to come up with a working principle for a permanent force field on my spaceship which will only permits guest while simultaneously deny strangers or foe. The following are conditions applicable to my force field:

1. Ability to transition between transparent and opaque for different viewing experiences.
2. Rigid enough to withstand a direct hit from a 10 petawatt laser blast.
3. Served as a permeable membrane which allows authorized/recognized spaceship to slip through unharmed without the need to power down.
4. It can display advertisement in 4K UHD.
5. Personnel can lean on it safely.
6. Air tight.
7. Trojan horse-proof? (Optional)

Note: kindly provides explanation should any or all of the above mentioned item sounds absurd/ridiculous/incorrect/out-of-place/un-achievable.
