No, the student would need to already receive a job offer and have that company file a petition on the students behalf. There is no such thing as a working visa to look for work- you must find the work first, then you can apply for a visa.

The application fee for a US visa (where you're coming from doesn't matter) varies depending on the type of visa. A tourist (or other non-petition) visa is $US 160. Most petition-based visas are $US 190; a few are more expensive. This is a processing fee and is non-refundable, even if you don't actually get the visa. There also may be a visa issuance fee that varies by country and depends on reciprocity. This is only charged when the visa is actually issued. For Ghana, there's no issuance fee for any type of visa. Ghana is not eligible for the Visa Waiver Program (which allows people to use an ESTA instead of a visa and is cheaper).

Can a US green card holder marry a filipino and petition for a spousal visa to the US
Yes. You can apply for a US F4 visa ( Family Preference Visas), which is immigration status. To do this, your brother must first file a petition to the USCIS. If the organization approves the petition, you can apply for this visa at your country's embassy. Just note that a limited number of F4 visas are issued per year. So processing time may be a bit long.I recommend visiting the Visa Library website for more information. On this website, you can find a complete guide on the US F4 visa application process.I appreciate if you please like my comment if it was useful to you.
