Note on CT sources: The CT adventure Exit Visa makes it clear that getting off-world is not only NOT a right, but a readily locally deniable privilege. This adventure is in the Traveller Book, and is set on an Imperial world; it appears in another publication on a different Imperial world.
"Another publication" in this instance being
The Traveller Adventure. (Odd that they put that same scenario into both, eh?)
To answer
Hal's question above, no, a person may not necessarily just "walk onto a starship" just because s/he is an Imperial citizen -
IMTU there are indeed regulations that must be followed, and sometimes negotiating them is a nightmare as shown in
Exit Visa. (I have a variant of this that involves getting export permits for speculative cargo.)
However, the underlying principle is one of Imperial citizens moving freely between worlds - as
Sigg Oddra noted, worlds that make this difficult or dangerous tend to end up as amber or red zones, which can kill any planetary economy dependent on trade. A planet may deny entry for a criminal record, for example, but any world that begins restricting Imperial citizens from a particular planet without due cause (like, say, a war in progress) or restricts access to Vargr who are Imperial citizens is most likely in violation of its member charter.
For me, the take-home message of
Exit Visa is not that an Imperial citizen cannot be denied entry or exit without due cause - the scenario is about
delays resulting from regulation, not the denial of rights of movement as a fundamental right of citizenship. Yer gonna get yer visa stamped at some point - the question is, can ya get it done in time...?
