International PhD students have a variety of visa options to choose from, depending on their country of study and personal circumstances. In the US, for example, international PhD students can apply for the F-1 Student Visa, J-1 Exchange Visitor Visa, O-1 Visa, H-1B Visa, or EB-1 and EB-2 Employment-Based Immigrant Visas. Each visa has its own requirements and benefits, such as the F-1 visa allowing for temporary employment for up to 12 months, and the O-1 visa being for individuals with extraordinary abilities in their field. In the UK, international PhD students can apply for a student visa, which is valid for the duration of their PhD, or they may be able to study without a visa if they have been granted asylum or recognized as a refugee.

Visa options for international PhD students in the US
International PhD students in the US will typically be on an F1 visa, also known as a student visa. This allows for the possibility of employment in the US for up to 12 months in a role directly related to their field of study. This is known as the Optional Practical Training (OPT) program, which allows F-1 international students to gain work experience in the US.
Students on an F1 visa can work on-campus for up to 20 hours a week during term time and full time during the holidays. Off-campus work is also an option, but strict employment conditions must be met, and students must wait until they have completed their first academic year.
The F1 visa is typically the starting point for graduate students, and once they are close to graduating, they can apply for OPT through their school's international student services office. This will allow them to stay and work in the US. The OPT is usually valid for 12 months, but those who have graduated from a STEM program can apply for an extension of up to 24 months.
There are other visa options for international PhD students, including the J1 Exchange Visitor Visa, which is for those participating in exchange programs that promote the interchange of skills and knowledge in areas such as education and science. This visa is usually valid for the length of the program, and there is no maximum of five years, as some sources suggest. However, J1 visa holders will need to return to their home country for at least two years at the end of their program.
Another option is the H1B visa, which is a temporary visa for skilled foreign workers. This can be obtained through academic or non-academic jobs, but there are differences between the two. The academic H1B is cap-exempt and is for employees of "not-for-profit institutions of higher education".
The O-1B Work Visa is another option for those with extraordinary achievements in film, television, or the arts. This visa is initially valid for up to three years and can be renewed for up to one year at a time.
Finally, there are Employment-Based Immigrant Visas and Green Cards, such as the EB-1 and EB-2. These provide a more permanent status than the J1 or H1 visas and make it easier to change jobs.

Visa options for PhD students in the UK
International PhD students require a visa to study for a doctorate in the UK. The visa options for PhD students in the UK are:
Student Route Visa
The Student Route Visa is a points-based system that replaced the Tier 4 (General) student visa in October 2020. It is available for full-time and part-time PhD courses. The key changes to the Tier 4 visa include:
- Students can begin their visa application six months before their PhD begins (previously three months).
- There is no limit to the time spent studying postgraduate qualifications in the UK.
- EU, EEA, and Swiss nationals are considered 'low risk' and are exempt from proving they meet financial requirements.
- Students may not need to prove their language proficiency if they have studied an English-language qualification in an eligible country.
Graduate Visa
The Graduate Visa is available for students who have completed their PhD and allows them to remain in the UK for up to three years. To be eligible, students must have studied with a Student Visa or Tier 4 (General) Student Visa. The Graduate Visa lasts for two years, and three years for those with a PhD or other doctoral qualification. It cannot be extended, but students may be able to switch to a different visa, such as a Skilled Worker Visa.
High Potential Individual (HPI) Visa
The High Potential Individual Visa is for those who have been awarded a qualification by an eligible university. The list of eligible universities is based on rankings from around the world, and UK universities are not included. Applicants must have received their qualification within the last five years and prove they have enough personal savings to support themselves in the UK unless they have been in the UK with a valid visa for at least 12 months.

- The university where you are doing your postdoctoral research will apply for your J1 visa to the US State Department's Bureau of Educational Cultural Affairs.

F1 visa requirements
The F-1 visa is a non-immigrant visa that allows international students to enter the US and study at institutions certified by the Student and Exchange Visitor Program (SEVP). The F-1 visa is for academic students who are enrolled in an "academic" educational program, a language-training program, or a vocational program.
To obtain an F-1 visa, you must meet the following requirements:
- Institution certification: The college or university where you plan to study must be approved by SEVP Immigration & Customs Enforcement.
- Full-time enrollment: You must be enrolled as a full-time student at the institution while your academic term is in session.
- English language proficiency: You must meet the required English language proficiency score of the institution you are attending or be enrolled in courses that will help you improve your English proficiency.
- Sufficient funding: You must prove that you have sufficient funds available to finance your studies and living expenses while in the US.
- Valid passport: Your passport should be valid for US travel for at least six months after your program completion date.
- Home country residency: You are required to have a residence in your home country to return to following the completion of your degree.
The F-1 visa process starts when you get accepted to a SEVP-certified US university. After you receive acceptance, you will receive a Form I-20, which you will need to apply for your F-1 visa. You must then complete the DS-160 visa application and schedule your visa interview. During your interview, you will need to present your Form I-20 to the consular officer.
It is important to note that F-1 students may not work off-campus during the first academic year, but they may accept on-campus employment subject to certain conditions and restrictions. After the first academic year, F-1 students may engage in three types of off-campus employment, including the STEM Optional Practical Training (OPT) Extension.

EB1 and EB2 visas
International PhD students have several visa options if they wish to remain in the US after graduation. These include the F1 visa, J1 visa, O-1 visa, H1B visa, and EB1 and EB2 visas.
EB1 Visa
The EB1 visa is a first-preference visa for foreign nationals with international recognition and very accomplished careers. It is only applicable to three occupational categories:
- EB1-1: Aliens of Extraordinary Ability
- EB1-2: Outstanding Professors and Researchers
- EB1-3: Multinational Executives and Managers
The EB1 visa is highly sought after and therefore has the highest and most stringent requirements among all green card categories. To qualify, applicants must prove they are in the top percentile of their field, whether that be in science, arts, business, or athletics.
EB2 Visa
The EB2 visa is a second preference, employment-based immigrant visa for foreign nationals with advanced degrees and exceptional abilities. It is another way of bringing talent to the United States. The EB2 visa category has more flexible eligibility requirements, making it a more accessible option for a wider range of professionals.
To apply for an EB2 visa, applicants must fall into at least one of the following categories:
- EB2-1: Professionals with Advanced Degrees
- EB2-2: Individuals with Exceptional Ability in Arts, Sciences, or Business
