Houston: seafarer FAQ
- Is shore leave allowed at Houston?
- Shore leave at Houston: USA requires a C-1/D crew/transit visa for shore leave at every US port. SID alone is NOT accepted at the gate. CBP may grant a D-1 (depart on same vessel) or D-2 (depart on a different vessel) parole at the gate. Apply for C-1/D in advance via travel.state.gov before joining a US-calling vessel.. Shore leave policy is set by the port authority, the flag administration, and the visa regime of United States. Confirm with the agent before stepping ashore.
- What visa or shore-pass do I need for Houston?
- Seafarers calling at Houston on a vessel are generally exempt from regular tourist visas under Convention 108 / 185 (Seafarers' Identity Documents) if their flag administration has ratified the convention and they hold an SID. The standard document is the seaman's book + ship's crew list. United States may also require a shore pass issued by the agent. Confirm before you board the vessel — visa rules vary by nationality and by recent immigration-policy changes.
- Is there a seafarer welfare centre at Houston?
- Yes — 2 seafarer welfare centres are listed for Houston in our directory. The centres are typically run by the Mission to Seafarers, Stella Maris (Apostleship of the Sea), or a regional ministry, and offer wifi, transport, shop, chaplaincy, and advocacy. Walk-in is normal; no appointment needed.

- What's the nearest hospital to Houston?
- Most major ports have a port-area hospital with seafarer-accustomed admissions; the welfare centre and the ship's agent can both advise. For serious cases, the nearest international hospital is normally in the same city or the next major city. The nearest major airport is William P.
